One possible reason is that the chair frame has bent making excessive tension on the belts making it difficult/impossible to unclip or they simply couldn't get access to the buckles....
No doubt this will need to be resolved....
Possibly another example of a real-life incident over a calculated one. There was a lot of side-wards motion in this incident, perhaps that bent the seats differently than predicted as well.
