With all due respect, why are you trying to explain what you admittedly don't understand?
The net effect is that you now start drifting. Since aircraft aren't designed to handle side loads, landing in a drift is not good.
You even up engines thrust along with use of rudder to center the aircraft before final touchdown. Not that this really matters since the drift you are referring to is countered by the crosswind, that is the designed purpose of this technique. Give the aircraft drift into the wind to avoid drift from the cross wind, hence needing less of a crab angle.
those aircraft are being CERTIFIED at their MAXIMUM CRABBED LANDINGS
No, they were just a compilation of high crosswind landings. The original search was for certification, the search for that video was just high crosswind landings, not certification.
some of which used a forward slip maneuver to align the nose just prior to touchdown.
Landing one, left to right xwind, right landing gear hit first with no slip.
Landing two, right to left xwind, left gear hit first with no slip.
Landing three, left to right with left gear hitting first, small slip.
Landing four, right to left with both gear at the same time and no slip.
Landing five, right to left with left hitting first, no slip, pro verse roll.
The last 2 were go around.
1 in 5 put a partial slip into the wind during landing. The others likely had a small effect from pro verse roll leading to the a slight bank away from the wind just prior to touchdown.
On a completely different note, wasn't there an aircraft designed with rotating landing gear so it could land sideways? I think I remember seeing something like that on TV long ago but am unsure.
