That does seem to exclude Dave's interpretation, since that would
require two straight runs.

It does indeed.

If you regard horizontal and vertical strips running the full width
and height of the wall from every accessory as 'no go' zones for
inserting fixings,

Which, IMHO, you have to do as you have no idea from looking at an
accessory which of the four possible directions are in use for buried
cables. OK you can take the accessory off and assume(*) that any sides
that don't have a cable leaving them are safe. If you do that with my
interpretation you are still "safe" though.

(*) As we all know "assume" makes an ASS out of U and ME.
