I think Russell gets most of it out of his system just by filing the lawsuit, announcing the song, etc. He doesn't feel the need to actually follow through because he's already gotten the kick he needs just by starting the process. So, we end up again and again with Russell instigating things, but then dragging his feet and issuing wails of resentment as if everyone else were imposing on him, rather than vice versa.
You eat a sandwich and feel pleasantly full and satisfied, and then the waiter insists that there are 20 more sandwiches you must eat -- I think this is how Russell experiences it.
