The THS did not travel to (-) stop. It stopped short, something less than a degree. Neither did it "start" after one minute of SW.
Take a look back at Takata's pic of the Recovered THS. Note the damage to the NU end of the screw. Impact? Possibly. But the damage suggests collapse of the thread collar opposite the implied direction of travel at water impact. Something like an airload, not a water contact.
