I don't know for sure but I bet this was part of a penny pinching cost analysis up front.
I recall when moving to a new site setting aside some time/budget to ensure that every cable was labelled (so, for example, we could trace ethernet from port on switch to patch panel to underfloor cable to floor jack to desk cabling to desk port) and set up a simple database to keep the details.
Work was killed off by accountants as an expensive luxury, after all cables didn't move often did they?
Fast forward to a minor flood under the false floor taking out some (but not all) systems. Fortunately some of them were in the finance and commercial group.
Suddenly it was "why can't you reconnect me NOW??". Money was paid for an 'after the event' recording of wiring by external people (which cost about 5 times the 'saving' up front).
Still at least it was better than a LONG time ago [Vax and VT220 era] when I saw one person labelling connections by yanking out an RS232 cable from a patch panel, waiting for a call "My terminal's died", asking which room they were in and making up a label and then plugging it back with "I think that may fix it" and getting pathetically grateful responses in return.
