TECHNICALLY NO... The plane line is defined as the base line at the Inclined Plane (where bottom of the plane where it comes into contact with the ground). Look at 10-5 pictures, the lines and the clubhead. If you hit the ball off the hosel by tracing the Plane Line, then you have a bent Plane Line.

....but I said "when you Trace with the ClubSHAFT"...I mean specifically- the ClubSHAFT. It comes out of the Hosel. So if you trace with it....technically (I put that in CAPS but it could be italicized too) it would hit the Hosel, no?

i.e.- if you were to trace the Plane Line (that goes right through the ball) with the ClubSHAFT (as if it physically extended out the sole of the club for a few inches....).

It should not hit the ball but hit to the inside of the ball as what they are demonstrating is the travel of the golf shaft to the plane line, the club face sit to the outside of the club shaft.

That's exactly what I mean.

I hope I have properly understood what you said in your post...
