I realise they are different things, but in some cases, they tie back into the MET, no? And in other cases, they don't tie back in, instead they are all at equipotential, not connected to MET?
Regardless of wether or not there are incidental ties back to the MET, supplementary bonding in a bath/shower room is to do with keeping everything which can introduce a potential at the same potential within the bath/shower room.
