He said he could connect once in awhile. It's more likely a server or two isn't following that rule than that his ident works randomly. I've been to many networks where ident is required on most, but not all servers (Efnet being one that did this in the past when I was unable to use identd. It may have changed since then, of course). I admit I've not been on quakenet, but I'm not sure why it would be any different.
