In the extremely rare case that Stipe wins this fight (I think it'll be a blowout for Jones), yes. Absolutely. Jon Jones will 110% request/demand a rematch.
Look, Jones has probably been the most vocal UFC fighter in history when discussing a "legacy" and what legacy means to him. He's made his money, and everything he stands for is dependent on that undefeated streak of his. A loss will shatter people's perception of him- and he's aware of that.
Make no mistake. Jones will cry his eyes out if he loses. But he's smart and understands that the only way he'll be able to salvage that loss is by soundly defeating Stipe in a rematch.
In other words, Jon Jones CAN'T go out on a loss. HIs legacy depends on it.
