That’s right. Such a device is not needed. He is doing it all with his skilled control of the sticks.
besides farming simulator? Look through the bowels of steam.
(never played it. It may have been throughly lambasted by a sarcastic costumed game reviewer who stands at a podium and lambasts the industry).

Thanks @Wally @tabularasa - and @L0ki for refreshing my faulty rememberator
Some years ago one of the European plant manufacturers had built an excavator that had applied the same technology as used in automotive regenerative braking to every ram on the machine and it worked in both directions. I think the result was a smoother running machine and a 25% saving in operational costs. Was that just a prototype? Are they a segment of the market - or is that technology filtering through?
Edit: I’ll just answer my own question as I’ve just come back from an internet exploration sortie.
Yes it was Volvo as I had guessed and looks like a regenerative system on every actuator was just for the concept machine. The production model seems only to be rolling out about now. Looks like the biggest bang for the buck seems to be regenerating energy lost from lowering the boom, explained in the vid - also for those that may be interested in current research: https://www.researchgate.net/publication/251617938_Research_on_the_energy_regeneration_systems_for_hybrid_hydraulic_excavators
