It definitely wasn't fake. If it were fake, they would try to make both guys look like hard asses. Chael was obviously trying to avoid a physical confrontation. Just look at his body language and what he said. The strikes thrown during the melee were also very real.
As a side note, had no help been there, Chael would have beat Wand's ass. Chael got on top, if he wanted to, he could end it quick with headbutts.
