That's exactly it; if he's on the top the rest of the stack is irrelevant besides the Boosting. If he's on the bottom, he doesn't get boosted and the characters get to whittle their way through a horde of minions (potentially getting stronger in the process, or using Great Cleavage) before they get to a much-depleted Xykon.
