That's not really it. He's moving his poi in antispin in relation to his hands while his hands move in a "box mode" 4-petal antispin flower. I don't know why he put it as Zan's Diamond, because from Zan that's something completely different. A concept really. Much easier than the anti-antispin which I have yet to grasp other than an antispin v anti-antispin antibrid. Too many anti's in the name I know...
