I think he's saying that killing the motor has a FE penalty in that when you restart, the injectors spew some fuel to get the cat converter going. So he's suggesting you shouldn't kill it if it's just a few seconds stop.

Dan, if you can give some kind of reference on this that would help. Aside from cold starts where a rich mixture is needed I haven't heard of a fuel squirt being needed or used.

Killing the engine at stops is a pretty standard FE technique for standard trans cars - at least among those very dedicated to FE. I think the general wisdom now is that even a 10-second stop warrants shutting down. I think we're going to need some fact-based references, not just a statement or a figuring-out.
