Topology can be thought of as "how the mesh components are organized", like which triangles share which edges, whereas vertex positions are the (x,y,z) coordinates. They are independent, as this slide shows.

Hard to think about sometimes, but valid topological representations can also mean that several edges span the same two edges (overlapping), which we've found to be the case in Assignment 2.
