Hm... Still leaves it a bit unclear. So, the character itself is a boy. But, the dev's going to treat him as a girl... Like, is he referring purely to the mechanics of the character to say that he'll have all the same interactions the female characters do? Or, is he referring to flat out changing the character and giving him a girl's model for the game? How is it possible that I can go to the post and see him getting banged and still can't tell... The chest seems male, (could also just be flat,) but can't see the important part to confirm. (These are rhetorical questions / thoughts, I don't actually expect anyone to have all the answers for these things.)
I do hope he ends up being male. He's cuter that way. Still, I think he's an excellent addition however it goes.
