Nice pictures. No information.

The oil jets are not actually for lubrication, their main purpose is increased cooling effect needed by the horizontal pistons in the 'L' configuration Ducati engine. Many turbo car engines use this same system to cool the top of the pistons. The oil absorbs heat just as water would do externally.

Nice piece of animation.

Good question, but I'd have to assume that since Shell worked directly with Ducati on the development of the oil, there is probably a particular additive package that works best for the characteristics of the V-twin and desmodromic valves.
I'm sure each oil manufacturer would have several reasons and explanations about why their particular blend is best!

The oil jets are not for lubrication as such but predominantly for Cooling! The wash of extra oil keeps the piston at a reduced temperature. The vertical cylinder does not need it as the oil is spread more effectively across it compared to the horizontal.

Thanks for the explanation!

Why do only the front pots have oil-jet lubrication?

Good question, I don't know how precisely the animation represents the actual engine, maybe it's just for illustrative purposes.
