The question is: are these really changes in the jet's banking angle or just corrections of the horizon indicator while the ATFLIR LOS is moving from left to center?
The jet's speed and altitude are very constant, and if you stitch the scenes together to get one big overview both the jet and the object seem to maintain a constant angle with respect to the horizon while the horizon indicator seems a bit off. So maybe too much trust is placed on the horizon indicator in the ATFLIR display and the jet does not bank very much in reality:
