Actually its worse for gas mileage then if you left it in gear. When you are in gear your momentum going down the hill is turning the wheels and turning the crank, but your throttle plate is closed so you aren't using any gas. When you shift into neutral your car needs to keep the engine turning by using fuel.
Ps dumbest quote of the link is:

Avoid Excessive Idling
Idling gets 0 miles per gallon. Cars with larger engines typically waste more gas at idle than do cars with smaller engines.

No kidding its 0 mpg cause your not going anywhere but thats not actual consumption.
