The feel should be that the clubhead blurs in a straight line, but the blur is in fact making an arc since we have an inclined plane.

The only time the blur does not make an arc and moves in a straight line is if the plane is striktly vertical.

Homer said the Plane was "vertical" then paused and said, "slightly inclined." The clubhead will always make an arc, since the club is orbiting your left shoulder as it is the top of the radius. But, you can see the second hand of a clock moving in a straight line, if your eyes are on the same plane of motion. It doesn't mean the second hand stopped moving in an arc.
