Not from a regulatory compliance point of view, but I would be very scared of catching a wingtip in one of those swells and cartwheeling in at 60 KTS.
IMHO there is absolutely no reason not to pull in these circumstances as the video of the landing clearly demonstrates. Why risk it?
As for landing on water causing back injury, there is one case of a pilot who pulled over water at low level who did hurt his back but was still able to exit the aircraft and swim, he made a full recovery. There has been no other injury in any other water landing under CAPS including this one.
