I'm pretty sure it was because Sadie was the biggest coattail rider of the season, lasting 11 episodes, but having some importance only in 3 of them (ep 6, 7 & 11). This is especially visible when she does nothing for three episodes straight. Although some prefer Sadie because she got more screen time and thus more moments (her "Marshmallow eating-freaks" line), there are some (me included) who prefer Katie for the exact same reason, as she at least didn't unnecessarily last too long in the game. I'm sure one half of the side voted for Sadie in some of those categories, while the others voted for Katie.
