Probably not a misalignment but rather the effect of winds aloft and the vortices created by the wings at the wing tips.
Vortices will cause the outboard exhaust contrails to move outboard and then back inboard. The inboard engine exhaust contrails are not effected by the wing tip vortices and actually move down from the flight path of the aircraft.
Winds aloft (a crosswind) can cause what you see. Three are parallel but one is divergent outboard but then comes back inboard.
