I think it's very clever the way Bill has done this.
He's made sure he can veto anything until Moshini proves himself, Moshini will have made promises to Bill and if he follows through with them then Bill will sell him more shares, that's the way it is working from what I've read.
That would only work if Bill owned the other 50.1% of the club. But he doesn't. Moshini could simply buy a few shares off one of the small shareholders and have complete control of the club.
