Well, if I remember right, I believe he said in the comentary that since the brother & sister were a package deal, (you know, like Biff's 3 goons) you can't have one without the other. If they used the brother's scene, the audience will get confused if they didn't show what happened to the sister to. But, since the actress was pregnent at the time and couldn't be in the movie; they had no choice but to cut out the brother's scene to.
