I think you are confusing terminology... "the universe" includes everything, really. But, it is often used just in reference to the mass and energy of the universe that is expanding. Used to refer to everything, including the void that said mass and energy is expanding into, implies that the universe itself is incapable of changing size, as it is an infinite void.

If gravity were to cause the mass and energy of the universe to eventually start contracting again, the universe itself would still have that infinite sized void out there.
