I have watched that video before and it makes more sense to me by far than any other version of reality I have heard concerning what NBC means. “Natural born” is a term I used to hear in other contexts when I was young and it was understood to mean that if you were for instance, “A natural born killer”, you could never NOT be a killer, that is what you were born to be and you could not be otherwise even if you wanted to with all your being. Apply that idea to citizenship and it rules out anyone who might have some possibility of being something other than an American citizen AT BIRTH. That would mean someone born to two American citizen parents and subject to American jurisdiction from birth, not someone who might have some claim to citizenship in another country.
“That would mean someone born to two American citizen parents and subject to American jurisdiction from birth, not someone who might have some claim to citizenship in another country.”
Correct.
