You guys are all being sarcastic right? he didnt wheelie on purpose. He was looking through his legs to see how much of a lead he had on the guy behind him. having his head upside down probably disorientated him so he didnt notice the wheel start to come up causing him to react too slowly to stop the wheelie.
standing up like that while accelerating on a straight away will make the bike wheelie since it shifts the weight up and back.
