I don’t have the slightest clue what you are talking about, and I don’t think you do either.
I made myself clear, you have to go by the laws of the other country to determine citizenship to that country, not the laws of this country.
If the laws of the country make you a citizen simply by being born in that country, then you are born a dual citizen and not NBC.
If the laws of that country don’t make you a citizen simply by being born in the country then you would be a NBC.
If a British couple has a child in this country the child is both an American citizen and a British subject. He would be a US citizen but he wouldn’t be a NBC of the US.
To be an NBC, then all must be true, mom and dad citizens of the country where the child is born.
If one isn't true, then not a NBC.
No matter what anyone's or country's laws may be, no matter where one thinks citizenship comes from, soil or either parent, all agree about the citizenship of that child.
That is the purest definition of natural born citizen. Nothing else. Everything else is a lesser standard that opens the door to other claims to that individual, given how citizenship had been defined in the historical record the FFs would have had to study.
That's all I'm saying and why I think that's what the FFs would have meant by stating such in the eligibility requirement. It's the only office so defined and I believe that's why.
