He crosses the line at the top, but even then, at 1:06 that's close enough to on-plane to make the point that it moves substantially more off plane at the onset of Throwout, which is the important point and the one which you two are dancing around. Had he stopped his BS at :55 with the shaft parallel to the plane line and started down, what would your evasive dance step be?

As for not seeing a golf swing at that link, you might ask your dance partner how he managed to see it.
