That's just Heather being Heather. And Owen wasn't in the bottom 2 because even if Heather's alliance all voted for him then he would only have 3 votes tops, the other girls would have given 3 votes to Duncan as well. So Izzy may or may not have changed her vote after hearing what Leshawna said.

OR alternatively, Chris was just being Chris, and Duncan and Owen tied, but he still said Duncan had more votes for drama purposes. Wouldnt be as dramatic if he removed Owen and Duncan at the same time.

I think the writers did this intentionally to make it an open ending of speculation.
