Fast-Draw (Ammo) covers every step of quick reloading. The roll speeds up the whole procedure, whether that's a few seconds with a removable magazine or a minute with a powder horn. It isn't really a task that's sensitive to handedness, as it involves both hands anyway. I'd say it's the mention under Fast-Draw itself that's somewhat redundant . . . but I suppose you could be forced to operate one-handed, have the right perk for that, and be using the wrong hand.
