The mains pivot. They are made that way. A conventional X-wind technique would drill the engine cowl into the ground. Notice how easy the roll is after touchdown (including the absence of smoke from the wheels). Which means the tires arent blown. Any conventional aircraft landing with such a side load without pivoting mains would have blown the tires on touchdown, followed by tons of smoke, followed by tons of sparks, followed by flames trailing the gear. Wise up people.
