That's what it looked like for the attacker, but not for the defender. In this instance the defender had two units in good shape, one right by the disputed cluster, but the game ended abruptly when the last attacker unit in the cluster was destroyed. The defender wasn't given a chance to retake the victory hexes.

Sometimes the end game logic is quirky. I had one game where I was the attacker and had taken all the victory hexes, with the final hex taken in the first extension turn. So the next turn I did nothing except hit the End Turn button and the game extended another turn. I did this for 12 straight turns thinking the AI was up to something although it didn't have much left in the way of units. Finally I moved a unit and hit End Turn and then the game ended. As long as I didn't make any move it looked like the game would have extended indefinitely.
