There does not seem to be any way to tell where they lifted the plane from. The view of the wing tip is blocked..

Look at 2:11 in the video. It looks like they lifted it along the main spar and determined the plane was nose heavy. I'm assuming that's the correct balance point.
Yes - the view is blocked. But it looks like they tried to verify the balance was acceptable and apparently they thought it was.
