Yeah. I don't have a pen that supports twist in hand to see what its driver reports. But my understanding is that if you hold the pen at a particular position in space and just twist it only the twist value should change and not tiltX/tiltY.  @SummerLW do you happen to have the stylus that reports twist handy to test this?
