In order to DFCO, the revs have to be above 1500, which takes considerable more energy than idling at 700. Sure, no fuel is being used during DFCO, but it still requires energy, which is provided by the kinetic energy of your coasting vehicle, which was previously provided by gasoline (accelerating up to speed). You can feel the energy loss - the way the vehicle decelerates quicker when you are in DFCO vs neutral coasting.

My car will hold DFCO until idle for that speed so I usually downshift at 850 rpm. I can't get a good enough line of sight to be able to coast to a light EOC but I can in DFCO and have it turn green so I don't use brakes.
