Why would gas run out under 01 leSabre when tank got full? on 2001 Buick LeSabre

My Son was putting gas in his 01 LeSabre custom and gas started pouring out underneath the car for a few seconds and stopped. Anybody know why this would happen? Thanks!!

Faulty gas pump nozzle auto shut off. Or gently topping off tank and overfilled it!
