Personally, I think that this is pretty insignificant. If the car is going to roll, it is going to roll if it's in gear or in neutral-there's not that much more resistance to change the dynamic. Making sure that your ebrake is engaged and your wheels are turned properly on hills is more important.
Thanks for the helpful tip!
