I would imagine shutting off the engine while at idle is the same as shutting it off at a higher RPM--except with more fuel. Don't see any point to it whatsoever.

I think what flash is saying is that modern bmws and other modern cars as well continue to fire one or two of the cylinders after shutdown to burn off any fuel and smooth out engine shutdown (more refined)
