This is good.... At this point, the bed leveling is active and correcting for X/Y movement. Your bed is physically very level. I suggest after you do the G28, G29 and see a similar matrix get defined that you move the nozzle 100mm on X back and forth. You should see the Z axis twist back and forth. And do the same thing on the Y axis. You should see repeatable movement on the Z.
