There's another difference, and that is that other humans can learn and study that mental model (which is why "readable code" is a goal — the code is a physical manifestation of the model that you, the programmer, has to learn), and then the model can be tweaked and taught back to the original programmer, who can then think of that tweak in the future. Programming is inherently (in most cases) a collaborative art, because you're working with people to collectively develop a mental model and refine it, smoothing it down until (as Christopher Alexander said) there are no misfits between the model and the domain.
