An engine can be turned over with no fuel going to it.
What it can't do is give you any power with no fuel and this would then slow you down (engine braking).
Think of it this way if you rev the engine out of gear it slows down when you take your foot off the accelerator as the fuel going into it has been reduced this is the same when in gear and manufactures have work out that above a certain rev range you don't need any fuel going to the engine at all to keep it turning over.
