Except this class is not the only one that by its own class features makes you no longer qualify for the class...
So where do you draw the line? If you go by the CW rules, then you're making multiple Prestige Classes no longer legal.
You can't use a hard & fast rule because of situations such as this, that's the problem.
I think it's pretty obvious what the spirit of the rule is: don't use an item or some other way to qualify for a PrC and then ditch it once you got what you needed, as it completely eliminates the opportunity cost of the requirements - but you can't simply slap on a bandaid rule that then causes more mechanical problems.
That's a big part of the problem - the rules WotC will put out, such as the one in CW, don't even take into account their core rulebook options.
Is there a way to rule this so it makes sense? Absolutely. Is it in a WotC rulebook? No.
