The difference between the north and south buildings is that the south ones have an upper floor window. When an MG is garrisoned into these buildings, it can setup in that upper floor window and fire across the LOS blocking fences, provided another unit is giving line of sight. The north buildings however, since they lack an upper floor, cannot offer this line of fire.
Essentially, the LOS blocking fences in Poltawa's center only work one way, which probably isn't fair (or intended).
