Very good observation, although I'd say this is still just understanding at the micro-level. A lot of what is going on in communication between people depends just as much on what hasn't been said, what would normally be said in this situation, having an idea of what the situation is in the first place, what was said recently or the last time you interacted with this person (which could potentially be a very long time ago), etc. I do believe that a lot or all of this can be posed as CSPs though.

On my reading list is "The proper treatment of events", a book which "studies the semantics of tense and aspect" within a formal framework of constraint logic programming[1]. There is other similar work in this area, like "Good-enough parsing, Whenever possible interpretation:a constraint-based model of sentence comprehension"[2].
