It sounds to me like your approach may have caused them to decide the way they did. Were you "paraphrasing" the situation above? Or did you literally cut to the chase and tell them they hit a "point of no return?"
I understand trying to cut out unnecessary rules when you know the situation as DM. I do it all the time. But sometimes the players just don't get it and see it as a "gotcha" moment as mentioned above. They only see the two choices presented, one to go back and ensure their survival, or two to plunge ahead and take a risk to find the hidden DM "easter egg."
If instead you whipped out the "holding your breath" rules and went through the motions of the number of rounds, saving throws, Endurance checks, etc. maybe they would have seen more clearly that you were following the RAW and they were putting their characters at risk.
