Because your alternator starts to generate more power as you accelerate, as opposed to an engine at low speed or idle. The car reads this extra voltage from the alternator, which is trying to charge the battery, and tells the light to go off.
This is not normal on a vehicle with an alternator. You need to have the alternator checked as it more than likely needs replacing.
