I think a lot of women and girls have been tired of hearing from people outside of the world of softball that "softball is easy", and "baseball is harder".
It takes some doing for a high school boy to respect softball as a difficult sport. I think this video went a long way in helping improve the image of softball as a true sport. I always just saw it as proof of the legitimacy of softball, not necessarily a proof that baseball players can't hit.
That may be what they say or imply, I haven't watched it in a while, I admit. Maybe someone should take the video a step further and show the baseball player going through two weeks of practice, the adaptations he has to make, and his success or failure.
