I suspect that more than anything it has to do with putting the cabin and the counterweight at the same level in the tower, as someone else mentioned already. If you wander over to the Disaster Transport side of the tower, there is a little round access port at the bottom covered with an expanded-metal cover. If you take a peek through the expanded metal, you can see the counterweight appear as the cabin reaches the top of the tower.
In any case, if we assume that the counterweight is about the same mass as the empty cabin, then the two masses would hang in equilibrium at the middle of the tower. That's the theory, anyway...
