When the First Doctor deactivates the warning lights that caused the Doctors to fall into the trap, they pause for a moment and then go about their business, with, aside from a brief trip to Dovie's house, no evidence that the events of the day are recalled by any of them. Yeah, but the actual events weren't an alternate timeline created by the Master, but something that was reverted by someone else. Also, if they remember isn't relevant.
