First-hand account is pretty meaningless though as it is not as if we have a test case of them without the curse. Being merged or combined doesn't mean inseparable either. Plus, if they were separated there is no reason why he would have to retain all the memories. If he learned something while they were merged maybe he would retain it, but we can assume that soul and memory are different in this sense. He can access memories of the past people with whom Ozpin merged through their shared Aura, but his mind is still separate. Only memories he has retained in his mind will be kept in the event their Auras become separate again. We also can't really say who is dominant. In fact, it is hard to see how the most recent personality could ever really be dominant when they presume all of the past interactions are their own.

Honestly, your understanding of it is a bit dire. Oscar will never be able to be Oscar in any sense ever again. A normal life hardly means being oblivious to all the things that have happened, but it does mean being able to enjoy the peace that has been created. Keeping Oscar as a merged personality would honestly be like the curse is still in effect. Understand that as a "curse" the merging in itself is one aspect of it. Leaving them merged is keeping the curse in effect. While they could do that with your rationalization, it is hardly necessary and means there is no potential for Oscar to have a genuinely happy ending. Given that Oscar is truly an innocent in all this it would be kind of bizarre to have it end that way unless it is a generally dour ending rather than a happy one.
