You have to be an Alien first for anything therein to apply.

You're right that the entire thing is titled "Aliens and Nationality." But the section at hand talks about who's a citizen at birth. Regardless of whether you think being a citizen at birth makes you a natural born citizen or not, clearly someone who's a citizen at birth was never an alien. So no, you don't have to be an alien first for the section to apply.
