They are the same part, just mounted in a different location. I'm not sure exactly where the oil temp sensor is located, but from diagrams it appears to be adjacent to the oil pump.
I challenge you to show part 13621433076 "Temperature sensor water/oil" mounted anywhere on S65/S85 engines where it is measuring oil temp. You won't find it. There is only 1 count of that part and it's on the waterpump thermostat housing not for the oil. As i said above, either the oil level sensor doubles as a temp sensor or there is no oil sensor directly measuring oil temp (unlikely).
