Lower vapor pressure is better. Mogas has high vapor pressure. Oil premixed would tend to lower the vapor pressure (as well as octane, as you stated), but not enough to measure/detect IMO.

Since the oil is harder to vaporize it should reduce the tendance to vapor lock. I always get crossed up on vapor pressure, higher is harder to vaporize? I sure you get the idea.

PS the oil can reduce the octane level if mixed in high enough quantity although at the 100:1 needed for the rotary I doubt if you would even notice it's there. Bill
