It's not only you, I also sometimes get confused by it (see for example [1] and subsequent messages). Maybe the operational model could be clarified a bit. I also think it would be better if the UAX29 didn't use ignore rules at all, so that going from rules to implementation is more straightforward --- though I understand it may make the spec harder to maintain.
