There's more math in play. Your opponent evidently hurt his knee and may have trouble defending on his feet. If you let him take top he can just go into a claw ride not use his knee and take 30/40 seconds off the clock leaving very little time to get a takedown and prob no chance of a stall call (one at most if backing up at end). Go on feet have more than twice as much time to get takedowns also time to get 2 stall calls if only defending, favoring that leg and backing up. Might even get lucky with feet to back. If you moneyball this with all the probabilities of stall call, td, time etc you chose neutral. Do I think Bono went thru all the math - no, but he made the right call by luck or intuition.
