Not buying it. I can do both types of landings. At the end of the crab you still touch down on one wheel. So that can't be the reason.
I do both, also. That said, the max landing weight of the A380 is 851,000 lbs. I don’t have that issue in the Mooney.
Also notice that the pilot flying touched down on the mains, before kicking out of the crab. That was not a power off landing.
