Fast forward to 2.45m and see what "stirring the pudding really looks like." Note in the B737 video the twitching of the right knee. Note the difference in the aero video. Hence I suggest the B737 was a headwind turbulence landing not a X-wind landing. The former reminded me of my dog dreaming on front of the fire.
