Yes, once you know more about a domain, you see larger, more organized chunks when you look at data in that domain. There were studies that showed how amateur Chess player see individual pieces where Chess masters see piece-arrangements. Etc.
I would still say that programs are quite different from any natural language text in that they require a sustained effort to learn "what really happens here" as opposed to "what general kinds of things are being done in the different parts of the program".
A murder mystery is a genre where "one little detail" often is where the whole direction of the story is said to go. But that's usual a single discreet gotcha, added for theater. A program often consists entirely of such things, added not for theater but because computation can't help but work that way.
