I'm someone else who renames things after writing the code to start with. It's not that my understanding is incomplete - it's more like I'm using different parts of my brain for holding the general shape of the code and coming up with words to explain it. If I'm trying to get the shape of the code down before I lose it, then I'm thinking about what it does and how it does it. When I'm naming variables etc I'm thinking about explaining what it does in a way that's clear to me now, me later, and whoever else has to understand / maintain my code.
