X & Y pressure, indicating direction of a swipe motion?

Then it sends the pressure x and y. Note that I have no idea what this pressure is, as two numbers for pressure make no sense to me. Also, sony's own diagnostic test screen has two numbers for pressure which don't make sense either, so maybe they're just irrelevant numbers.

The pen lift message comes just once with its own sequence number.
Is X & Y pressure related to direction? So for a swipe are X & Y being updated to indicate the direction of the swipe motion? I know you can take the difference between successive events, but if the hardware does this more efficiently in relating directional pressure, that's a nice feature to exploit!

Best, Mark
