Thanks for explaining, I kind of understand it now, but what if the acceleration is > 2G, then gravity won't be enough to simulate it, and I'm still a little skeptical that the user won't feel the rotating and "slowly move back" to original position, but I've never used a VR headset so I might be completely wrong here

Your body's not that good at measuring acceleration. Sure, it'll be hard to convince your brain that blood's pooling in your feet, but being leaned way back will provide a pretty convincing >1g forward acceleration feeling if the visuals are right.
