I'm not sure that pronouns have anything to do with it, either. Urianger pretty much straight-up asserted that Nael was a male and not a female in the non-cutscene dialogues following Turn 9, and even went on to speculate that Turn 9's female Nael may have been been constructed from the memory of some woman contained within Nael's memories when Bahamut rebuilt him.

However, all this was speculation on Urianger's part. He knew Nael was a man because the Garleans knew that Nael was a man - and this lore book entry asserts that the Garleans knew Nael was a man because Eula had tricked them! There's no inconsistency; it was entirely reasonable for Urianger to believe what he did. And, because of his speculation, Eula's masquerade will likely remain intact in perpetuity. For us as players, though, it finally solves the mystery of, "Who was that woman that Nael was rebuilt as?" Answer: It was Eula, Nael's sister - and there was no rebuilding. Nael was Eula in disguise all along.

Honestly, this answers things satisfactorily for me. Especially now that I know the whole gender bender was created due to a miscommunication between developers. XD
