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.
