If I stimulate a second formation on a separate run, won’t the second shot simply reinflate the fractures created by the first shot?

No. If the second GasGun tool is placed at a different location from the first, the fluid tamp between the zones will force the energy to be expended on the formation immediately adjacent to the second tool. Fracturing is restricted to within a few feet vertically of where the tool is placed (see energy loss calculations).
