I use EOC on 3 big hills in my commute with my auto trans, I do use the starter to restart though. On the hills I get about 1.5km of glide so the car is off for only a minute or two and I don't think this is going to hurt anything, as I don't think auto transmissions use pressurized oil for the bearings, and even if they are there is no load in the transmission, everything is spinning freely.
I guess its a bit of a risk but I'll take it. Even people with manual trannys doing a EOC in pulse and glide are "abusing" the engine. Running the engine at low rpm, high throttle puts additional stress on the cooling and oiling systems, and then suddenly the engine is shut off not allowing the coolant and oil take heat away from the internal hot spots. On any high performance racing type engine this could quickly kill it. Fortunately passenger car engines are over built (or understressed) and we can use them this way. I'm going to assume my automatic tranny is the same and can take some "abuse" for 6 minutes a day.
