When are those parameters assigned, only during posting or they are always available magic words?

For example I made welcome message for IP users. Using instead of $4. Looking at a recent contribution it seems that wikia translated into IP/@comment-Wikia-20130616064442! ... I am not certain why(maybe I should have used base name) but it's not what I want.

If I replace with $4 in the template will the change be reflected retroactively?
