It's the exact opposite: If it requires legislation by congress under their power to create laws of naturalization, then, even if you are born a citizen, it is the opposite of a natural born citizen, who would always be what he is regardless of any legislation.
By that standard, there is no such thing as a natural born citizen, because the same law also recognizes people born here:
SEC. 301. (a) The following shall be nationals and citizens of the United States at birth:
(1) a person born in the United States, and subject to the jurisdiction thereof;
...
(7) a person born outside the geographical limits of the United States and its outlying possessions of parents one of whom is an alien, and the other a citizen of the United States who, prior to the birth of such person, was physically present in the United States or its outlying possessions for a period or periods totaling not less than ten years, at least five of which were after attaining the age of fourteen years...
My notes:
1. There is no difference in status at birth between paragraph (1) and (7)
2. I have heard several people advancing a theory that those born outside the US are "naturalized at birth," but the definitions in this statute put a monkey wrench in that:
TITLE I GENERAL
DEFINITIONS
SECTION 101. (a) As used in this Act-
...
(23) The term "naturalization" means the conferring of nationality of a state upon a person after birth, by any means whatsoever.
