Having just watched the video, it reminds me of the old blue screen shots when people are pretending to be driving cars: lots of sawing away at the wheel without any corresponding movement from the vehicle. Much of the “turbulence” here appears to be self-induced by flailing away in what are not exactly challenging conditions.
In my outfit, that approach would have been classed as unstable for multiple reasons, with a mandatory GA. Not a great display of airmanship here I’m afraid...
