There is indeed a balise on the side of the track that does tell the train to cut power and then reapply it afterwards, without the driver having to operate any controls.
However it is accepted practice to shut off power at a neutral section in case the APC magnet is defective and doesn't cut the power. It also helps reduce the possibility of arcing and also stops any jolt within the train.
