I think you should just give up on the notion of obtaining a speedy answer to your question in the forseeable future. Although lacking much MMZ expertise, as a bystander or so, I would simply say that it was a story planning fault and not something of importance, since even to this day there have been no attempts in clarifying this by anybody from the staff behind MMZ series (as far as I know from frequenting this wiki and such).
