I’m no good at consistent execution, but what follows is my understanding of what should be happening.
It does depend on swing path. I’m not sure about Justin, but other golfers famous for playing a fade (Nicklaus among others) advocated a square face to the target while swinging along a path inside the target. The club head was square to the target at address, but the body alignment/swing path was open to the target. He said if he wanted to draw it, he still squared the club head to the target while aligning closed to the target.
But if the hands are manipulating the club face more open or closed than at address during the swing, or the swing path does not parallel body alignment at impact, a compensation at address could work without aligning with either stance or target as long as everything repeats. The same principle as above should still apply, but it will look different as the degree of compensation might be shaded more open or closed to the body alignment if the swing path for that player is not parallel to stance or if the club is manipulated to a more open or closed position by the swing.
