Are Warrior disciplines supposed to share a cooldown?

The way discs are set up sugests to me that there are supposed to be three separate cooldowns for discs, one for the defensive (10 min discs) one for the 3 minute damage (30 min discs) and one for the spike damage discs (60 min discs). But I don't think there was enough evidence to prove otherwise hence all discs share the same cd. Thats just my speculation however, I think this answers part of your question.

This wasn't changed until LDoN, long after the p99's timeline:

All Disciplines now require an expenditure of endurance to use. They 
still have a re-use timer, and they can't be used more often than the 
timer allows. 

Disciplines have now been divided into a few different timers.
