I think you may be correct that even humans would increase probability of a repetition continuance with N up to a point. The difference could be that humans are using a much larger compressed historical context, so when reading something like Moby Dick, the prior for any serious repetition is absurdly low, and it never comes up.
Also humans read fundamentally differently through vision, and even when the retina is focusing on just a word or two at a time, you are also getting some bits of signal for surrounding future text, and big repetitions would be fairly obvious.
