I think what you're thinking of is the white smoke normally given off by charcoal when it's lit. I think some people initially question the minion method because they assume that when the lit charcoal hits the unlit charcoal it will give off the same ugly white smoke. For whatever reason the minion method doesn't produce that white smoke. It probably has something to do with the charcoal smoldering and not actually burning with flames but that's just a guess.
You might also be thinking about adding unlit on top of lit. I would avoid this personally because it might smother the fire and that would lead to an unpleasant taste in the meat. If more fuel is needed I would add coals that were lit in a chimney.
