I don't see why it should be the case at all, and I would like to see the evidence that it is more likely. It sure is a possibility, but realistically you have to compare it with the possibility of a military coup with traditional autocratic military. The only plausible explanation for that phenomenon is that democratic group (military in this case) is more efficient/willing at asserting its own status as a group than an autocratic (hierarchical) one. And that is, in fact, internally contradictory. If intent of the military as a democratically-controlled social group was to overthrow the democracy in the state as a social group, then it would be acting against the very existence of ts own democratic process.
