This seems like a good example of why you shouldn't be doing staged decompression dives off a boat with a dive-naive crew.
If I were under an obligation and an emergency recall was sounded, I would assume that someone was in desperate straits, and I would shorten my deco as much as I thought I could, and get on O2 immediately upon boarding. I would not do a deco dive off a boat without O2. And I would be pretty danged livid if I surfaced and found out the boat had given an emergency recall just for drifting divers. I WAS just a drifting diver, and I have been before, and if you stay calm AND the boat has seen you, you're going to be fine. The guy who cut his deco short, however, may not be.
