Yeah that maneuver's called "crabbing" -- looks scary, but as I understand fairly typical for cross-wind landings

Basically just flying into the wind a little bit to cancel it out, so that relative to the ground you're going right down the runway, even though the nose is pointed the other way. Then turning down the runway at the last moment so the landing gear is pointed the right direction when it hits the ground

30+ degrees is definitely on the higher end though
