Robot continues to move after timer expired


lets say the kids use button E to raise the robot for a high park. They press E, they put down the joystick, and the timer runs out but the robot continues to execute the E command given before the match expired.

Is this legal? Can the robot continue to move autonomously after the time expired? Does it count as a high park? Or is it up to the referee to guess the robot height when the time expired?
