you also have to consider that it's written a bit tongue-in-cheek, so the stuff like "sexually charged scenes" is probably meant as a bit of a hyperbole to make a point that it's just a bad idea to make Leia Luke's sister.
Yeah, you're right. But I hear this kind of thing quite a bit. "EEEW! Luke was all makin' out with his SISTER!!" Which never happened... I mean, yeah it's a bit awkward that Luke obviously thought she was hot, but... she was. So there :P
