Every modern fuel injected car has fuel cutoff under certain conditions.

Coasting in neutral - you can almost certainly do it with the engine running, without damaging anything. As for shifting back into gear, I'm not so sure. Maybe someone with more experience driving the Fords can jump in here.

Coasting in N with the engine OFF requires that the transmission can be "flat towed" (drive wheels on the ground) in N. Otherwise you could be risking damage due to lack of lubrication.
