Consider the case where:
M1 and F1 are US citizens abroad
They have a child, M2. M2 is a considered a "natural born citizen."
M2 never leaves that foreign nation.
M2 has a child with F2 (a US citizen abroad): M3.
M3 is not a US citizen as his M2 was never resident in the United States.
In the context of the Act, it seems like that clause is to prevent a chain of "natural born citizens" who never stepped foot in the US. It doesn't block citizenship by other avenues, it limits the naturalization act itself.
The act also limited citizenship to race and moral character. The entire point is no where is Jus Soli the metric, even the 14th avoids it and that amendment was ratified under a suspended constitution which makes it invalid.
