My new Shimano XT 8100 rear derailleur has the switch with on and off positions. From that I found on the web, it is a "clutch" and I must turn it off when removing the wheel. I can shift the gears with the switch in both positions without noticing much difference. Web says the clutch makes the gear shifting better, still.

I was not able to find technical explanation, how does this this clutch actually work and how it influences the gear shifting. A clutch like in a car would disengage the engine (me?) from the wheels. It does not look doing anything the like. What it technically does?
