I guess it would depend on frame size, bar height, and size of the bar roll. If you were nervous you could add a bungee, but I didn't bother.
There are a few brands of handlebar bags that hang in this location that also have extra cords (or maybe bunge) to the sides that attach to the drop bars below the brake levers to keep the bag centered.
