This was not a definition, but an extension under Congress's power to make rules of naturalization (which, by definition, has nothing to do with Natural Born citizenship!) to treat children of overseas Americans "as if" they were natural born, IOW, a legal fiction, without actually being clear that they are well and truly natural born and eligible to be President.

To treat somebody as a NBC who isn't a NBC is unconstitutional. You think the Founders were actually doing that?

Congress can of course define rules of Naturalization. But they can't define new rules for being a NBC nor can the make laws to treat somebody like a NBC.

The most likely scenario for the language in the 1790 Act was that they were reiterating the common definition of what it means to be NBC.

Well no, which should be self-evident in the post you just quoted.

Again, the 1790 act was overturned by the 1795 Act, which eliminated “natural born” status for children born overseas.
