- The highlighted fragment can be interpreted as "if there are several passages on the map, then it is necessary to destroy the guards at EACH passage in order to pass through." In my opinion, this sentence is unnecessary and the meaning is clear without it.
I also think these points are unnecessary:
5.14.3. It is allowed to use the bug of viewing the opponent's cities.
5.14.4. It is allowed to break more than once on a Guardian of the City (GO) that contains an upgraded stack.
