DISCUSSIONS on “Rules for online games in HoMM3 and formulas for calculating player rating.”

Regarding the game with Oldboy, I have a couple of questions about the Balance template:

1). I have an exit leading to a neighboring zone through a guard post, but below it, approximately 1.5 turns away, a mine was generated, through which I can pass into the same zone (a bugged passage), and there are no guards nearby.
We open the rules and see:

2.6.5. In the absence of a passage guard, free passage from one zone to another is allowed.

So, do I understand correctly that I can freely pass through this passage regardless of whether I have defeated the guard above or not?

2). How should I understand

1.4. Restart at the player's request, if the only road leads to the Guardian Outpost (for the 2SM4d(3), Jebus cross, Balance, Nostalgia templates). It is taken on the day this fact is discovered, but no later than day 115.

Very often, only 2 roads are generated: 1 to the Guardian Outpost, the other to a dead-end home town. And the rest of the exits from the starting location lead through impassable terrain. Is this a RE (random event) or not?
And if there is only 1 road to the Guardian Outpost, and the rest of the exits, including the home town, lead through impassable terrain?
