I agree with the general perception that the "go around' decision should have been made earlier, the first time the airplane skipped to the left (regardless of who was flying the airplane at the moment, it's still the left seat's call. He's the guy who buys the accident). Having said that, as David suggested, it's possible that the 'tower' winds may have been considerably different than the winds at the approach end, and may have been within published aircraft limits (which are listed as "demonstrated"). In Fifi (A-319/320) it's 39 knots crosswind component; there are no 'total wind' limits. Different airports have very different wind reporting abilities.
On the cross control/dihedral effect comment, contrary to 'normal' aircraft, I am told by my good friend and Airbus captain that Fifi does NOT use opposite aileron to counter rudder. The electrics in the airplane are supposed to compensate, requiring no pilot input...I'm not sure I buy all of that, but I'm not Airbus qualified (Boeings primarily, with one sojurn to the DC-10).
In general, the video is not complimentary to commercial aviation, IMHO.
