He sneaked an edit in just in time, by the looks of it.
Steel conduit with low voltage wiring in it is always considered to be an exposed conductive part. Being buried does not alter that.
So being buried has no bearing on whether something can be touched?
What a strange understanding of materials you have.

i was going to make the same comment for metal backboxes, although i believed that only applies to conduit if unsheathed singles are used?
Metal backboxes certainly require earthing regardless of whether they are immediately touchable, imagine if it was in a metal stud wall or someone pushed a metal pipe down the void etc. It's the containment for the terminations, unless people would argue a sheet of plasterboard is sufficient
How many Class II items can you think of where it would be hazardous to shove a piece of metal through the outer casing into the internals?
