You're absolutely right. That was my mistake. I meant to decrease the rightmost 1, mark the 3 and 2, and then replace any marked items w/ the current expression. I'll fix my previous comment so you can see what's going on. Now that it's no longer referring to itself, and is in fact lower than what we started with, it'll actually terminate this time.
