Is this some sort of complex in-joke?
Uh, no.
We JUST had someone in a thread (I'd link it if I knew exactly which thread it was) talk about Nintendo's way of trying to make it appear their stock and supply of items is limited, whether its intentional or they really do have short production runs. Nintendo DOES have a slower pace when it comes to replenishing stock as well, I thought this was somewhat common knowledge?
I'm not really understanding your question?
