What it is
Letting the engine slow the bike instead of the brakes, by staying in a low gear.
The long version
Inference — on a long mountain descent this is not a technique, it is the difference between arriving and not. A brake converts speed into heat in a small metal part; an engine converts it into pumping losses across the whole engine, which does not fade.
The reason this matters so much on this circuit is transmissions. A geared bike has it. A twist-and-go automatic scooter has almost none, which is why the descent advice on a scooter is different in kind rather than in degree.
