Ifixplanes - We had this policy even before Helios. There are of course many other points to notice and rectify the problem, but I think there is no harm in having good processes in place to ensure things like this don't get left in those positions to start with i.e. the best method of detecting the problem is to remove it in the first place! Obviously other things have changed since thing including the takeoff config/cabin alt warning lights as well as a mentioning it in the brief on first flight of the day. Its amazing that the AMM didn't require the return to the auto position - didn't know that until now (not that any of it excuses the flight crew from checking it)
