I'm sure it will be in the 'V' of the engine and be 'dry' from lubrication, other than lubricating the bearings of the shaft. I don't see any advantage to immersing it in the block, or trying to spin it up with oil pressure. That is already doing a very important job and you'd want to keep as little additional heat from the oil as possible while trying to moderate core engine temperatures.

I agree the principle is fine (very good in fact!), it's just the video at that point appears to be incorrect.
