The 1790 act shows what the Founders thought "natural born" meant (even after taking into advisement the opinion of a random Swiss scholar). Its repeal is irrelevant, given the 1795 repealing act does not even contain the term "natural born".
If it did, then they wouldn't have used the words "Shall be Considered AS", they would have said "Are."
"Shall be considered as" means "similar" it does not mean "same."
