ouch!! unlike the Kiwi's turning to windward with a jammed mainsheet. it looks to me that they were asleep. it looks like the main stayed in the same position thru the capsize and no turn to windward to dump the wind. that is exactly what happens when you are sailing along and a big puff hits and you don't react.
Read an interview (that I can't find now) in which the skipper said he dumped the traveler then fell to the low side so he couldn't dump the mainsheet. Your basic self-inflicted wound...
If you look closely he slid to the middle console only, exactly where the traveler was and he didn't fell off the boat until after capsize. Some speculated that downdraft from the helicopter caused them to flip, some blamed hydraulics and others the crew.
Funny thing is that it was photo shoot for the marketing campaign and it worked, they got lots of publicity

watching the video the position of the boom remains the same throughout the capsize. clearly asleep at the switch. that is exactly what happens when you are too slow releasing the main sheet and turning to windward. probably every cat sailor has experienced it. it illustrates how good the Kiwis were in avoiding the capsize in the america's cup.
