I was more interested with the physics of his turns which from what I can tell closely resembles the physics of a PMTS turn. Skis are designed to turn when put on edge, but how to actually do that without introducing sub-optimal movements is not obvious nor intuitive so we need PMTS. I think this snowboarder is operating with the same core understanding that the optimal way to make a parabolic (ski or snowboard) perform is to put it on edge. Since the medium is different, the snowboarder uses different movements to achieve the PMTS result: pure edge-to-edge tipping of the parabolic while compensating for the directional change.
I find the video instructive because ultimately any argument against PMTS is really an argument against the fundamental reality that skis are designed to turn when put on edge. The fact that this core principle carries over to other parabolic snow sports should be the final nail in the coffin of any non-pmts theories about skiing.
