Yeah, they usually don’t jiggle like that. However, the plane was very stable prior to that and on what looks like a normal glide slope.

One thing I just learned is that there was a pretty stiff crosswind, so they had to yaw to the left to straighten out. This normally means the right wing gets a bit more lift so you compensate with right stick to keep it level.

A wind gust at the right time would have caused the wing to not gain lift and the aileron correction could have sent the wing into the ground.
