My players and I talk about how they're trying to do something interaction-wise, what it is they want to do, and use that as a guide for how they actually roleplay. One of the players doesn't care too much for that, so interacts however he feels at the time, and the others often have to clean up after he's done a bit of damage.
I agree that it's a good guide, and doesn't have to be used all the time.
