Thank you! That makes perfect sense.
I was thinking the wing would raise due to the yaw at last seccond, but the aerodynamics of a landing a swept wing jet were never explained in our training. You would think it would be worth 30 minutes, or so

This crosscontrol in the flare is also be called a slip.
Any aileron input error should be to the excess which would put the upwind gear down earlier than the downwind. Some guys do that on purpose.
I've seen more sideslip to landing sideloads on big jets caused by the guy who wants to fly it like a cub than sideloads by guys who did not decrab enough.
If your airplane does autoland read how it corrects for X-wind.
Even on aircraft designed to land in a crab, such as the T-38, most guys naturally gravitated to a decrab in the flare.
