She certainly had more topspin than that. But since the video is meant as an instruction manual on the basics and general tips, maybe the clip is meant to illustrate a basic topspin shot? The basic shot mechanics that a beginner would produce would be something like that...that topspin backhand is still probably better than any I could hit haha.
