If everything is loose (as it should be), hanging onto the dolphin striker crossbar near the windward hull should cause the boat to pivot into the wind right away.
I was always taught to go hang on the dolphin striker on the windward hull to keep the boat from continuing to roll over. It does make sense that it also creates a pivot point. I really cannot think of a time where the boat tried to sail off without us onboard - it has probably happened but I don't recall it.
It's all sort of automatic to me now (having done it way too many times), so it may not be coming across correctly.
The idea is, once the boat starts coming up, get to the old bottom hull (when capsized), which will be the new windward hull (when righted), pulling down on the dolphin striker cross-piece.
That should kill two birds: puts you in the right place to keep it from rolling all the way over, and for you to be the pivot point to make it turn into the wind.
