In this case, I would assume the Hypno has been brainwashing the trainer over a period of time, which is called "conditioning". You can't hypnotize somebody once and have them immediately change their way of thinking and behaving forever; it's a gradual thing, where you keep putting them under and encouraging these changes until it comes naturally to the subject to think and behave the way you want them to.
Real life hypnotherapists use methods like this, but the reason it works is because the suggestions the hypnotists are saying are things the subject already wants to believe or do. For example, hypnotizing someone to stop smoking would only work on a subject that wanted to stop smoking.
And in the hypnosis fetish community, feminization hypnosis is the #1 seller.
