There are literally dozens of possible scenarios which could cause the aircraft to end up in that position, so the "I think it was....." seems a little daft to me as very very few people have the facts at hand and none of it will be validate until the BoI have completed their investigation.
Mind you, I'll never forget the GR1 that ended up just off the runway at Dhahran after the NWS went to full left deflection when the pilot selected 'HIGH'.
