Jeez, look at his angle of attack. I'm no expert but I would have gone around for another pass.
AoA is the horizontal attitude. What you saw was cross wind. The problem was that cross wind was outside of the demonstrated capacity of the airplane.
Crosswind landings are nearly always the case, airports are fixed unless it is a carrier but they have other limitations, like length and hitting the second arresting wire
. Anyhow, crosswind will result in the plane pointing off the direction of travel relative to the ground, it is airspeed which keeps planes flying, not ground speed so they point into the vector addition of the airspeed and wind.
You see dramatically the result of attempting a landing outside of the demonstrated maximum, the high side wing cannot be brought to level because the aileron has insufficient authority to keep the plane level. Cross wind "pushes" the wing up due to the upward bend to the wing called dihedral.
