AT netural downhill

Excuse the dumb question but i really dont know much about car engines.
I have an 09 370 with Automatic Trans.
I live up in the mountains and my trip down is all down hill. In my previous car which was a stick, i jsut coasted down in netural. is it bad to do this with an AT. Its about 20 miles and i dont have to put it back into gear but maybe 1 or 2 times brienfly? is there even a benifit to doing this (like saving gas?) I do notice i am able to build up more speed while not in gear and thus can coast longer. please advise.
