I believe Kohana just warped reality just a little bit there, The Club room is inside the main school building, therefore if she was outside the clubroom she would be in the hall. (unless she moved even further away unspecified) This means she would be incapable of seeing the roof of the club because that would be the roof of the entire school, or more semantically, the next floor. 


What I am trying to say is that it is basically impossible for such a movement to occur with such fluidity from the hall to the top of the building. That is all.
