It stops engine braking from slowing the carThis was the right answer

When coasting, the engine is disconnected from the drive to the wheels. This means that the engine's resistance can't be used to help slow the vehicle, especially when travelling downhill. There will be a little coasting every time you change gear; this can't be avoided, but it should be kept to a minimum.
