Look at the video. Wind from the right. On approach ailerons seem to be at roll right position for flying back to runway centerline. At time 00:38 ailerons are still at roll right position (correct), then touchdown with left gear slightly before right gear and then aircraft bounced off. Then at time 00:39 ailerons seem to be at neutral or slightly roll left position, what allowed for gust of wind to roll the aircraft to the left so that wingtip touched runway. Then was the last moment to go around and it went well.
