Quest's controllers have some gyro+motion assistance in them which Rift lacked, so they can still estimate tracking for a second or two outside of sensor range, which is enough for swiping behind or doing over-the-shoulder gestures.

What, Oculus Link stuff? Not done it personally (I own a Rift, my friend a Quest) but it's still in beta and still finicky with the USB3 cable/port. It's just installing the Oculus Rift software and it should auto-detect your Quest.
