I saw that and was going to post it here. You beat me to it :)

That is frankly the best defense for the contraversial lightsaber I've seen. It makes far more sense now that the blades would originate from one focal point inside the hilt, not from 3 separate emitters. So as he says, even if a blade does cut through a side emitter, the blade itself will still be underneath to deflect it. That's the theory I'm willing to buy ;)
