The plane went through a maintenance cycle in-between the flights; it was suggested that the maintenance caused the chosen AoA sensor to flip twice. I'm not sure of the exact mechanics of this, but it's conceivable the maintenance crew performed a full engine or board computer boot cycle. Therefore, when the pilots started on their flight, it was the second warm-up since the previous flight, hence the same sensor was selected.
