My guess is that rounding the offset mark in reasonable wind the skipper stays out on the wire while the crew raises the kite. Then they stay like that until the first gybe and probably swap then.
+1. good for higher wind transitions, as boats tend to nose-dive when transitioning from close-hauled to spinnaker angles (and crew is somewhat forward getting the halyard/daggars/sheets/main). Driving down on the wire does help a bit with visibility, but as mentioned before having the crew on the wire gives a bit more leverage when sheeting. And, if you do it right, you can slap the driver silly with the spin sheet if (s)he drives like a goon.
