My grasp on is the engine is "turning" replicating a running motor , accept without any fuel consumption , respectively outputting no torque.
If less fuel is supplied then the idle requires the engine would shut down, If one was to supply less fuel then idle consumes and not cutting it off completely would be wasteful.
not all cars have the DFCO , I think it started showing up on *most* cars around 1999 or 2000
