"It is important to emphasise that the anti-skid protection does not apply pressure on the brakes, but only relieves it. So, to perform a differential braking technique, the pilot should reduce pressure on the side opposite to the turn, instead of applying pressure to the desired side."
Considering this mechanically; supposing this is to be used during slick conditions, then applying enough pressure to the wheels opposite the desired turn direction should cause those wheels to lock up and the only response the anti-lock system has would be to completely relieve pressure until the wheel spins up to match the rate of the wheels on the other side, during which what ever braking is applied to the inside of the turn will still be available.

If the conditions are not so slick then the wheels do not lock up and the anti-skid system does not participate and there is no reversal.
