The question is, why did two AoA sensors, the one from the flight previous to the accident flight, and, (after having been changed), the accident flight AoA sensor have the same, identical incorrect AoA value?

You need to reread the preliminary report on JT610. The left AOA sensor was replaced prior to JT043 on the evening prior to the crash. Despite its malfunction on that flight, it was neither written up nor replaced prior to JT610 the next day.
