It sounded as though Johhny-O-than wasn't happy with how Bungie handled the stockpile spawning properties. It looks like we might be stuck with a poor spawning system for that particular gametype, although he did mention a potential workaround.
I now suspect that someone screwed up the stockpile game type script to where all respawn zones on the map are activated and the person couldn't figure out what was wrong, so they decided to "make" a zone they thought would suffice. Of course, I am SPECULATING here, but that is my gut feel.
