EOC with automatics?

So EOC'ing works great for manual transmissions, but what about Automatics? Is it always a bad idea? It's harder to turn the car back on than in a manual, and as far as I can tell, automatic transmission fluid will only circulate when the engine is on, but I have yet to reach a solid conclusion about it. I feel like the parts that are spinning in the tranny when in neutral would splash the fluid around and keep those moving parts lubricated. If it really does hurt the tranny to be moving with the engine off, how long/fast can you go without damaging it? I've heard that you can keep the engine off for up to five minutes without causing damage. Any insights on this subject?
