This is complete nonsense, go into any car without starting it and pump the breaks.

The ABS system is based on monitoring the way the wheels move and comparing it to how a car can move, in particular since the car is either moving or not, if just one wheel is stopping but the others are not, that's clearly wrong and the ABS tries to prevent that by reducing braking for that wheel. Going from some minimum speed to zero on all wheels is fine, that means now the car is stopped (or, for example, you went off a cliff and are actually now flying through the air - ABS can't help you in this case).
