It just shows the power of Cesaro. There is a video around where he did it for like a minute and a half, it's insane.
Kayfabe wise it pumps a lot of blood to their heads and leaves them feeling a bit out of it, and puts Cesaro over as a super human because he doesn't get dizzy.
Plus the one I'm talking about puts the guy in a torture rack and spins, then drops his hands to his side and keeps going. It's ridiculously impressive, and the 80,000 strong mania audience will dig it I reckon.
