My feeling on this is that Vitor wanted a higher ranking (or at least higher profile) fight than Tim Kennedy, so he turned it down based solely on that. I think all the rest is just posturing and media shenanigans. Pure speculation, but I sense he's just biding his time until a better opportunity rises, and trying to associate himself with title shots in the meantime.
It's been mentioned that he could take Anderson's spot if Silva gets injured. The same goes for any of the other top ranked MW showdowns. With the title fight being at the end of the year, he has time to see how the division plays out, and then wait for an opponent (Munoz, Okami, etc...) that would make his fight a definitive #1 contender fight.
I don't think he has earned the right to wait for the next title shot, and I don't think it would be a good idea for him to do so even if he had. That being said, I'll wait to see how this plays out because I have a feeling that's not what he will actually try to do in the end.
