You will note that the left bogie is almost flat, meaning it is on the ground...
It has *been* on the ground, but as the aircraft has bounced back upwards, it has been lifted off the ground and has not had time to tip back to the usual "dangling" orientation on approach
That is correct nonsense. If you watch the video in slo-motion, you see it has been lifted up off the runway. You can see the puff smoke is behind the gear from the momentary touch, and when watching you can see the left gear land again. Too many frames to post here...
