I didn't get the reasoning behind why the cable changer necessarily
needs to be sceptic. Though it's no big deal in the end, since a
"subjectivist" (?) will be present at cable changes monitoring that
indeed the cables are being screwed in properly, etc..

Just to ensure that there is no collusion. The cable changer will be
making the choice of cables with his coin; the observer will make sure
he fits the right cable. The cable changer makes sure the observer
makes no communication with the subject.

Bear in mind that anything which goes wrong in this department will
tend to make the job of identification easier, not harder.
