there are a few things that work like that, if you want to globally set them you need to do it first, before connecting to anything(i'm thinking of nicks mnicks and anicks here specifically)
I actually disagree that it should set it to all servers as you might want to be invisible on one network but visible on another. I know on one server i mode -x when on others i dont for a reason.
....Although it(having to disconnect to set globally) is an annoyance.
