yes it is true that a referee must stop the clock by going out of bounds in the last 2 minutes of a football game. no-one knows why they were told to do this but now the rules have changed.
Short answer: Yes, but a 2008 rule change allows the clock to restart on a referee's signal. This from the NCAA rules: Ball Out Of Bounds (Rule 3-2-5-a-12). When a ball is carried or fumbled out of bounds, the game clock will stop, as always. Beginning in 2008 the game clock will start on the referee's signal when the ball is ready for play, not on the snap. In the last two minutes of the half, however, the clock will start on the snap as before, preserving the ability of the offensive team to maximize strategic use of the clock.
