I always thought that cross-drilled rotors were simply about increasing the rotors' surface for better heat convection (i.e. cooling). More holes produce more surface for the heat to radiate from. That and the spoiled aerodynamics (turbulence, ventilation) from the holes translates into faster cooling of the rotors. Looks like the plasma explanation is a more scientific way of saying the same thing.

I was not aware that they cannot be shaven just like standard rotors, though. Something to keep in mind.
