It DOES have to be warmed up (fully is how much?).
It is part of the conditions to be met for the car to enter diagnostic mode (what you are in if you successfully execute the 'pedal dance').
Why? Who knows. Maybe it was to minimize the chance that someone stumbles across it messing with their car in the driveway?
