I'm not sure this is entirely true, most textile factory workers could probably not just tailor and sew a shirt, they do exactly one part of a design, like a single zipper, and then hand it to the next person, much like anyone working in a factory.

If the boat is at 50 m the chances of getting rescued in time are probably so low that it may even make sense to try as a last ditch effort? If you remember to breath out on ascent. Hard to say...
Still, deciding that the guide should not try does not even make sense if there was only a 5% chance he'd make it, from the two tourists point of view.
Only because they mostly don't do the work themselves ;)
An odd decision, I would have thought he was a good diver, so presumeably also a decent free diver, knew the boat well, could alert rescuers to the trapped people, and would not use up oxygen when gone from the bubble.
