Exactly. The correct view of "kill -9" is not that you kill the process but that you order the process to commit suicide. If it's not listening, no amount of shouting is going to make a difference.
As another example, your CPU sometimes disables interrupts while it's processing one because what it's doing is too time-bound to be broken into. If something happens and it hangs, even pushing the reset button (assuming your box has one) will work; it takes power cycling. I had that happen, occasionally, when I was doing tech support and I'd have to tell callers to pull the power cord for a few seconds. (It also happened to my own box once or twice, years ago.) Once, the computer was a laptop and the caller had to go hunt up a screwdriver to take the battery out.
