I would argue that the "do something" button should focus more on where you are in the process than the process itself. The examples in the page all sound like the "start" step, instead they should reflect that they're finishing or moving the user on to the next step. "Submit" is generic, but at least sounds final. The reality, though, is that we're all guessing. Unless you go to the effort to A/B test something like that, it's just voodoo.
