All flying machines are to a more or less degree subject to some basic laws. One of which is the roll-yaw coupling. If a plane rolls it yaws, if it yaws it rolls. Therein lies the answer to how to fly a bus, particularly if you fly a crab approach. When you "kick off the drift" you better be dropping the wing into the wind. That action also prevents a drift downwind. Finally, a bad approach rarely leads to a good landing. Trying to get back to the center line at that late stage in that weather was not the smartest move.
