I think it’s how it should be. User should follow the ship’s movements and turn him(her)self on the spot or sitting in the swivel chair.
When motorized chairs are norm, perhaps turning chair with ship automatically would be the thing to do 
I remember there is an option to lock camera to HMD. Perhaps you can disable it on runtime during Matinee sequence and then re-enable it.
Oculus recommends never take away control over camera from user/HMD. So having user physically turn to follow ship’s orientation is the best way IMO.
