Carl: I think autopass is not over-ridden. It is just that in a game with the cube, autopass does not cut in if double is still an option. Several of us have been trying to persuade the GODS in BRAINKINGLAND that an autopass feature "until I can make a move other than double" would be a good idea, and possible speed some games up a bit.
For God's sake, I have been in a tournament which began 7 years ago and does not look like ending any time soon. I am over 70 now, and despite my (current) good health, I may not last to see then end of this one.
