We don't even know if Ozpin is the original soul. For all we know, he could be one of many; each time the body dies, the original host goes to the next person through a technique passed down from soul to soul, and the previous 'voice' goes off to the afterlife.

So say Ozking was the host before Ozpin, basically Ozpin would have been hearing his voice (and possibly talking to him during times he was quiet and unresponsive such as when he was watching Ruby during Initiation), and then Ozpin went on to the next host (Oscar) using the technique Ozking taught him. And in turn, Ozpin will teach Oscar the technique, Oscar will go on to the next host with everything Ozpin has taught him, and Ozpin will head on to wherever souls go when they die.

This would make the transference intentional, but in this case a fight over control would probably only break out in the event of the new host trying to assist Salem or utterly refusing at all to help save them world. Then the previous host would probably feel compelled by duty at the very least to either stop the new host or force the new host to continue the cycle and give all the knowledge to the next host. Perhaps if the old soul was in control of the new host's body and performed the technique, the host's soul would be sent to the afterlife and the older soul would continue on to the next one (basically 'skipping' a host).

This is all pure speculation, of course, but still. The fact remains that we don't actually know that Ozpin is the original soul and not simply the previous host to an older soul.
