Thought this might be interesting. I was delving through my photo's from a recent trip, and found this sequence. A good old fashioned drop in can be seen from two perspectives, depending on which one you look at!
I bet if I posted just one in both the Windsurf forum and one in the kite forum (with the offender being on the opposite vessel) there would be a few words said 
I like it, love cross overs, it's possible that's what the windsurfer intended, full marks to the kiter for getting it right.
