You know, what I take away again and again from so many of these threads is that a great many problems that arise during a dive could have been prevented entirely by a little more time spent on the boat, or on land, BEFORE the dive. In both the OP's case, and the one just above, the divers assumed that the DM was their buddy, or was at least going to accompany them to the surface. The DM appears not to have understood that, and certainly hadn't bought into it, judging from his behavior.
People need to realize that a group leader is a GROUP leader -- depending on the dive op, they are charged with more or less responsibility for monitoring the entire group, keeping them together, keeping them on the structure, and getting them back to the boat. Unless it is SPECIFICALLY discussed ahead of time, the dive leader is nobody's buddy. I do agree that, if a leader is aware that he has a diver down to 10 bar, he should take some kind of action to make sure that diver gets to the surface safely. But it was the diver's responsibility not to get to 10 bar in the first place!
If you are alone on a dive, ASK who you can buddy up with. If nobody wants to take you as a buddy, TALK to the dive leader about that, and make sure he either understands you will be expecting to dive with him, or have him set you up with somebody else. Don't get in the water until this is sorted out and you know who will be diving with you and who will be ascending with you. If the dive op sends single divers to the surface when they get low on gas, you should know that and be okay with it before you dive.
All of the problems in the original story, and in the subsequent story, would have been non-issues if the questions had been raised in air, where people can talk about them . . .
