Here is a statement about the Liouville's theorem in my textbook:
"Because we are unable to discuss the details of the particles' motion in the actual system, we substitute a discussion of an ensemble of equivalent systems. Each representative in the phase space corresponds to a single system of the ensemble, and the motion of a particular point represents the independent motion of that system"
I don't understand what it means by "independent" in the last sentence, does it mean the particles are assumed not to collide with each other in the real configuration space?
