I see key issue in "one move" reverse deployment to MAX REV which was, as said at aviaforum, common practice of this CPT (and as roumors are at RW in general). Added to mess their habit of using autobraking and autospoilers.
IF it coupled with "normal" landing, WoW swithes will allow reverser deployment and everything is OK. This time overspeed + side wind + empty a/c + wrong practice =
