I can understand what you state about the hosel rotating counterclockwise around the sweetspot axis when the clubface closes - from a conceptual perspective. However, it doesn't "feel" like the hosel is rotating around counterclockwise when I swing through impact - even though I can understand the concept.
I can easily understand the painting brush analogy because the handle is in the center of the brush, and the brush ends are rotating around the sweetspot which is inline with the handle - because in that situation the handle stays centralised while the brush twists. I find it harder to mentally picture the situation if the handle is at one end of the brush and there is a straight line relationship between the grip end of the handle and the one endpoint where the handle attaches to the extreme end of the brush - because the handle will have to twist with that end of the brush.
