I would suggest that this regulation specifically refers to the visible
green/yellow colour combination of the conductor. If the visible colours
of a conductor are green/yellow, then that 'exclusively identifies that
conductor as a protective conductor'.

However, if the exposed green/yellow conductor of a multicore cable is
fully oversheathed or sleeved in another colour (e.g. brown) at the
terminations, then IMO, the new designation for that conductor would not
contravene the regulations.

It's not that different from oversheathing the blue neutral in a switch
drop with brown sleeving to redesignate it as a live conductor.

Hang about - whilst I cannot put my finger on the reg this second, I believe
that using a green/yellow conductor for any other purpose is absolutely
verboten.

Give me a few hours - I think I can back that up...

But common sense wise - what if someone cuts the cable later, determines
an apparant CPC and bonds it to something exposed?
