The ring cpc should have been continuous if the face plate was in place. I am not sure I agree with earthing a circuit through the face plate screws but earthing the back box is just acceptable.
What is the extra cable skulking at the bottom of the box?
I think it's an SFCU, so load side cable (based on the tiles, probably on a kitchen ring).
I can just about accept the CPC of one leg in each of the two earthing terminals on two terminal plates, certainly wouldn't accept one leg in the backbox and one on the plate unless the leg to the backbox carried on (and was continuous) to the plate.
