Yeah. The pneumatic cylinders that pull the seats back have a mechanical "Gripper" on the end of them, spring loaded shut. It looks to me like what's happening is that the "pre-brakes" that start about 3/5 of the way up the tower, that were supposed to initiate the return to vertical for the seats aren't doing their job (or the resistance in the pneumatic cylinders is too great). So the seats don't return to upright until the actual heavy braking section - too late - and then violently swing out... faster than the pneumatic cylinders can extend due to the port size, so that spring-loaded emergency gripper lets go.
They'll need to open up the port size on the cylinders (ie, new cylinders) in order to allow them to extend quicker/with less resistance, so that the seats can tilt as desired during the pre-braking section. Then they'll be upright already (and far more gently), ready for the actual braking section.
