Thought it might have been a brainfart. :-)
I think the reason people ask for 3 timers is mostly not knowing. The USA Swimming, USMS, and NCAA rulebooks are a bit vague in the areas of timers required for records, and what you do when a pad malfunctions. My recollection is that the concept that you can correct a pad malfunction with a single button is largely based on established practice and interpretation, and is not firmly or clearly written in any of the rulebooks. Nobody wants to screw it up, so everyone over-prepares. (Which isn't a terrible thing... three buttons are better than 2, which are better than 1.)
The terrible problem arises when you have one human timer, and the touchpad fails, and it happens to be the one race that the timer was asleep and missed the finish as well.
