Well you put two heel groups vs each other someone is bound to get cheers, especially one with a catchy theme song.
Seth and KO were the faces
random wrestling fact that I feel a lot of people surprisingly don't know...
In the WWE, the Face team will ALWAYS be positioned on the left side to face the hard camera (on tv) with the heel teams back towards the hard camera. it's done so that you can see the emotion of the faces while they await tags
so whichever team is positioned to face the hard camera will always be the team you're supposed to cheer
