A 13 amp fuse can take 20 amps for a long time before it fails.

I expect a cable rated for 13A would also survive for longer than it
would take for the 13A fuse to blow.

Apparently showers (Riba seem to be either 8.5, 9.5 or 10.5kW) can
run from a 13A FCU with some 1mm flex

Doesn't his fix make a mockery of safe-zones?

yes.

It would have been better to move his switch down to be horizontally in
line with the cable.

Happy to show my ignorance, while 50mm from a wall corner is a
safe-zone, I didn't think the same was true behind an architrave for a
door way.
