Well, from this video, I would say there's a possibility of her having a mild form of schizophrenia. For those who didn't know, the whole split personality thing isn't schizophrenia, that seems to be common misconception. It's a disorder classified by disconnect from reality, delusions, paranoia, and in bad cases hallucinations and psychosis. Also, I don't see in anyway how this could be satirical. I mean, she could be joking, but that's not satire. That part of the OP tripped me up a little bit.
