Build is well on track
You have a separated system where as the piston is immersed in oil in the body. The oil is forced through piston {left row, middle} and through the shim{little washer looking things} stack(s) for adjustable compression and rebound just like the #2. The piston is different due to the new design as well as a set of added passages on the top of the shaft where there is a needle valve {middle row upper top} which you can adjust externally both the rebound and compression (sweep valve).
The next difference is there is a floating separator piston (top left middle row) that provided a barrier between the oil and nitrogen gas. The nitrogen on top of the shock is charged (in your case of 10 bar or {0.69 bar = 10 PSI} or 144.92 PSI) that pushed down on the oil pressurizing the oil to 144.92 PSI. The oil and nitrogen do not mix therefor you will reduce the chance of cavitation due to the oil mixing with the nitrogen much like a milkshake.
Your third difference is I designed the shock body with threads in place of groves for the use of a ramp system. A threaded body provided for much more precise and infinite pre-load settings. The shock design is modern and is still found on racing motorcycles in the form of a piggyback configuration. Due to the space limitations of the saddlebags, it was necessary for the shock to be a complete unit + cost saving measures.
Your forth difference is your shock is externally height adjustable, lower or raise at will. This is a task that must be done with the removal of the lower eye mount.
The ride quality + high performance compatibilities are superior to the #2 so when you are approaching the pyramids and the Sphinx, you can feel confident in taking the turns at a much higher rate of speed while enjoying the ride of a couch.

Internal reservoir

And what is inside of your shock, notice the piston, nozzle, and needle valve.
