They would almost certainly survive anyway if descent initiated at any reasonable time. I've often wondered why the airlines even bother with the passenger oxygen masks, but there are enough decompressions I suppose it is good to include. Also, you'd want it if descent to breathable air was delayed (e.g. flying over the Himalayas). In continental USA, could get down to 15,000 feet pretty quickly anywhere and that would be sufficient to keep people alive. Could have bottled oxygen until landing for those with lung disease.
Otherwise nothing I saw above was really incorrect...
