I think it's because Myrtenaster uses only Dust Vials, while Gambol Shroud has at least been used without specifically-Dust ammo or vials.

Basically, Myrtenaster only uses X, so it is assumed it is using X. Gambol Shroud can use X and Y, thus there needs to be some specification on which one is it using.
