That is a fact, and it happened the day before. And of course the recent Boeing simulator sessions with line pilots at Seattle showed that they all stopped it. But of course, they knew what to expect, didn't they. But they were 737-max airline pilots and not Boeing test pilots.

Purley from an investigative point of view and not as a pilot. If the prev flight used the stab cut out switches who and when would they be returned to the normal setting? Would a record of this switch change be made?
If they had been reset by maintenace or the pilots of the final flight might this not have been a clie something else was going on?
