In my experience, controllers are human [citation needed] and suffer from the same types of learning/knowledge maladies as the rest of us. Bad information gets passed on through the generations just like pilots.
The OPs example sounds to me like the controller version of "don't run oversquare" or "downwind turns are dangerous", or maybe more accurately something like "you can't log PIC while getting your complex endorsement".
