Um, yeah, that's the definition of "neutral".

Um, yeah, that's the point.

Engine braking means that the engine is slowing the vehicle down. That's because it takes work to just turn the engine around even if there's no fuel being sent to the engine (pumping and friction work). During engine braking, your engine is basically turned ino a giant ground-driven air compressor. It's actually the engine producing negative torque. Power is going TO the engine, not FROM the engine. From a fuel economy perspective, you almost always want to avoid engine braking.
