Not at all. It's engaged to the driveline and is kept turning by the car's momentum. Indeed, if you turn the switch off with the car in gear and moving, the engine will keep spinning till the car eventually stops.

DFCO is very common in modern automobiles.

The fuel cuts back in at idle power level when the engine speed gets down to some preset level just above idle.
