This really became more intuitive to me after studying German, where the idea of separable verbs was made explicit. I don't think things should be named "setInstanceUp" or anything like that, but you could see how "setUpInstance" could mean something different than "setupInstance" (an instance of a setup, I suppose). Same with "signup" versus "sign up", login/logout/etc. There are a lot of examples of these things where people confuse the verb and the noun, and the word split can be the most concise indication of which is which.
