It does help at some margin to make code more readable. Humans just aren't that great at reading and understanding code. It has been said: "Write for humans, not computers because computers will understand what you wrote no matter how badly written". So if you're writing code on a team, do your co-workers and your future-self a favour and write code that's easy to read. It won't run any better or with fewer bugs, but it will be easier to understand later, easier to be understood by others, and "wishful thinking here": easier to debug.
