M-200% No. 7

I found this scheme (2sm2c) in a thread about various useful things, but does it actually reflect reality?

I watched some generated maps with the "reveal map" cheat enabled, and it seems that there's one easy exit from the starting zone to a zone with a village, and another exit to a village that's heavily guarded. The opponent has the opposite situation. And this seems to correspond to zones 3 and 6. But in this scheme, both exits are identical.
Furthermore, zones 3 and 6 are drawn differently in this scheme, but I watched a generated map and didn't see any difference. It seems like both are villages.

Random roads - does this mean setting all the checkboxes in HD+?
