I don't know because I have no idea what data the modeling is based on. My guess is that it has to due with herd immunity. The model appears to be based on the estimated number of cases, which as others have pointed out, is believed to be about 7 times more than the actual number of reported cases.
Applying that formula to North Dakota, would mean about 80% of the population has already been infected. (reported cases 87,000 * 7/ 762,000)
Perhaps someone with some expertise on the modelling could weigh in.
