There are subtlties but basically they jybed while doing NOTHING to get to the other side of the boat.

Perhaps it was just practice for a fast dismount at beach.
Re grabbing the sheet off crew....stay cool, see crews learning curve and talk quietly to make gains in both sailing the boat the same way. If I was crewing I would be gone in minutes.
