Let me answer my own question first. I don't think one can out limp-wristing / limp-shouldering a gas operated action. After firing a shot, both the bolt and the receiver move backward due to recoil. The bolt needs to move faster enough than the receiver for the unlocking/extraction/ejection to work correctly. It is the relative speed that counts. In a gas gun, the bolt is always faster than the receiver (rifle) by the same amount, regardless the receiver's absolute speed. It works even when it is free recoiling. You can't out limp-wristing/limp-shouldering free recoiling.
Recoil operated and inertia operated sound similar, but they are indeed different. Instead of jumping neck deep into the minutiae, I just cut to the chase. We can discuss the details if there is enough interest shown.
Recoil operated. Free recoil: doesn't work. Butt stock against solid wall: works.
Inertia operated. Free recoil: doesn't work. Butt stock against solid wall: doesn't work either. The receiver (rifle) needs to be moving backwards and then be stopped abruptly. You need to have certain cushioning between the stock heel and shoulder, recoil pad, clothings, muscle etc, and yet you need to lean into the stock.
I was a bit surprised to learn our military chose an inertia operated shotgun. The design is on the finicky side. Shooting from hip, or any positions without firmly mounting on shoulder, could lead to unreliable cycling.
