Sorry, USC Title 8 section 1401 does not even contain the words “exclusive” or “allegiance”
The Expatriation Act of 1868 is codified in Title 8 section 1481. In subsection A, there are only two ways to be a citizen of the US. Either by birth or by naturalization.
Section 1101 specifically defines naturalization as a process that occurs “after birth”.
Therefore, if by the conditions of one’s birth, one qualifies as a citizen of the US, then one has never been and never needed to be naturalized. As such, they are a natural born citizen.
Further, the authority for the establishment of these rules is vested with Congress as an enumerated power according to Article 1 Section 8 of the Constitution.

Is there some part of the definition of the word “exclusive” that you need further assistance so to understand it’s meaning?
‘Citizen at birth’ and ‘Natural Born Citizen’ are two separate and distinct classes of citizenship.
‘Citizen at birth’ is defined by the laws made by Congress and Amendments to the Constitution. Thus, the definition can be changed at any time.
(BTW, the Naturalization Act of 1790 was repealed and the Naturalization Act of 1795 nor any other act since had reference to that special class of citizenship, ‘Natural Born Citizen’. They knew that ‘Natural Born Citizen’ was a term used in the Constitution and that Congress had to go through the amendment process to revise that term. In short, a ‘Natural Born Citizen’ was a person born of parents who were both citizens.)
Common sense and logic provides the meaning of ‘Natural Born Citizen’.
‘Natural Born Citizen’ is defined by the laws of nature and common sense.
When ‘born in the land and of citizen parents (note the plural form) there is no need for a law to claim citizenship; it is automatic as a ‘Natural Born Citizen’. No law, legislation, constitutional amendment or other man-made affectation is needed. No nation can long exist otherwise. Other classes of citizenship may evolve and change through laws, but not the ‘Natural Born Citizen’ class. (A law of nature, such as gravity, can not be changed by man-made laws. (A law that attempts to redefine ‘up as down’ will not prevent you from falling on your a** when you jump into the air; up is still up and down is still down.)
Definition of Natural in the Merriam-Webster Dictionary:
http://www.merriam-webster.com/dictionary/natural
Simple Definition of natural
1: existing in nature and not made or caused by people : coming from nature
2: not having any extra substances or chemicals added : not containing anything artificial
3: usual or expected
Full Definition of natural
1: based on an inherent sense of right and wrong
2: being in accordance with or determined by nature
Origin of natural: Middle English, from Anglo-French naturel
Natural implies lacking artificiality and self-consciousness and having a spontaneousness suggesting the natural rather than the man-made world.
Since the continuation of a country’s existance is dependant upon the progeny of it’s citizens, it is logical and common sense that all children born on that country’s soil to citizen parents are themselves citizens.
No law is needed, it is logical and common sense to understand that a nation can not otherwise survive if such progeny are automatically or legislatively excluded from citizenship. Thus, they are ‘Natural Born Citizen’s.
Common sense and logic dictates that no law legislated by mankind or Constitutional Amendment or provision defining citizenship can possibly be considered to alter the true meaning of a ‘Natural Born Citizen’.
Laws which dictate requirements of potential citizenship at birth and laws which dictate requirements of naturalization for immigrants, are not natural regardless of the name given to such laws, but instead, simply establish a different class of citizenship. (This is recognized in Article Two, Section One recognizes and mentions two of the classes of citizenship.)

Emer de Vattel, who also defined a ‘natural-born citizen’ in his highly acclaimed and influential “The Law of Nations, Or, Principles of the Law of Nature, Applied to the Conduct and Affairs of Nations and Sovereigns,†Section 212 (1758 French) (1759 English) (and referenced in most of the those SCOTUS cases):
BOOK 1, CHAPTER 19 Section 212. Citizens and natives. The citizens are the members of the civil society; bound to this society by certain duties, and subject to its authority, they equally participate in its advantages. The natives, or natural-born citizens, are those born in the country, of parents who are citizens.
