In terms of restrictions, yes. I think the real difference between the two is a parking lot test vs. real road test. Someone with only an M2 may never have: been on the road, been higher than low 3rd gear, used turn signals, used mirrors, etc...
Anyway, the point is that there is certainly a difference between an M2 and an M. Don't get me wrong; I'm not saying restricting demo rides to M is a good way to filter out test riders--in fact I'm kinda sad since I've only got an M2--but that's the way they're doing it because of the difference I listed above rather than difference in the booz restriction.
