There are ways of expressing those ideas that don't necessarily have to make a scene. I dunno. I personally would have rather seen her maybe hugging herself, or her two halves just being together or embracing each other. But when they're put into postitions so that it looks like they're kissing, then that is done on purpose to make controversy, in my opinion. I just think that the two Ayu's just about kissing each other is trying to be too sexuall. For my tastes, it took the idea of the two Ayus and took it overboard. But that's just me and two cents.
By the way, not all of us know Japanese and the autotranslations can be iffy sometimes. And it's especially hard to try to figure out deep meanings like that from an autotranslation.
