So? It's just a game where there is a guaranteed one game swing. Over the course of a 3 game series, a team could either gain 3 games, fall behind 3 games or do something in between. Not each of those things are a 2 game swing. At the end of a series sweep, it isn't a 6 game swing!
If the Sox beat the Royals and the BJ's lose to whoever they are playing today, is it a one game swing?
