Occupying reinforcement hexes?

[cillmhor]

Another newcomer's question. When reinforcements are due to appear on a map edge and that map edge is controlled by the enemy and not occupied by the enemy, do the reinforcements still appear on the map edge. And what happens if enemy units occupy all of the map edge hexes, an unlikely event I know. Does the enemy controlling and not occupying the hex invoke the within two hexes rule?

Again thanks in advance for any help.
