Homogeneous vs. Heterogeneous Equilibria

I know that homogeneous equilibria is when all reactants and products are in the same phase, and heterogeneous is when they aren't. But what exactly does it mean to be "in the same phase"?

To the best of my understanding, a phase is the form of matter (solid, liquid, gas), so "in the same phase" means that the reactants and products are all gases, all liquids, or all solids. For example, a homogeneous equilibria could have all reactants and products in the gas phase, whereas a heterogeneous equilibria could have some reactants and products in the gas phase and others in a liquid phase.
