Yeah, that struck me as a pile of bollocks. In fact if you want something to hang flat in a particular orientation then two holes like that possibly the best way to go. You can have a single thread enter from the back, cross to the other, and leave to the back again. It can't easily rotate without twisting together the two end of the thread, and the separation between them makes that harder.

Maybe the holes were for something else, but this logic sounds like they wanted to find an excuse to reject the simpler explanation.
