I hate to be that guy, but I think you're in the wrong here. And if I am, I apologize in advance... but...
It is my understanding the UFC only has to offer any fighter three fights a year, and is simply to fulfill the obligation on the UFC's part to make bout offers. The fighter can refuse, but they don't get paid or "show" money for doing it. The UFC just uses the fight refusal as a means to extend fight contracts and keep the fighter under control. And it doesn't mean fighters fight 3 times a year. Most don't, at least not anymore, lol.
Jon can't fight professionally anwhere else without the UFC's permission, belt or not. Jon's not just bound by the champion's clause, he's 2 fights into an 8-fight deal IIRC.
