Coasting in neutral - bad for economy?

The Department of Transport says in one its leaflets: "Don't coast downhill or towards lights in neutral as this uses more fuel" Is this true? The leaflet is called "Be a smarter driver and save money."

Yes. The engine requires a little bit of fuel to tick over while coasting out of gear. In gear with foot off the accelerator, the drivetrain turns the engine and the fuel supply to it is cut off entirely.
