I don't know if that's still true. While an automatic with the TC unlocked is pretty inefficient, they don't coast badly.

Both in neutral and in gear, at lower speeds (25 - 30 mph) where aero drag isn't an issue, my Jeep will coast practically forever. Then again, at those speeds, the thing actually coasts as well, or slightly better, in gear up to about 25 - 28 mph, as the engine is turning at, or just above, idle, and not dragging the Jeep down at all. Basically, that means that it's more efficient to coast in gear than to NICE-ON coast at low speeds, as the engine is using about the same idle fuel (as indicated by the instant mpg display), and still providing some motive power, rather than wasting it away in neutral.
