Two mechanisms. First, its ionization potential is lower than neon so the atoms have less voltage to accelerate them. Second and most importantly, the mercury ion is MUCH heavier than neon and so accelerates to a much lower speed across the potential than neon. A third effect is that the cathodes are coated with a thin film of mercury so many of the collisions are mercury on mercury.
