Spin Axis - Sidehill Lies

No.
Only your path and clubface affect the axis.
What side hill lies cause to happen though is a change in our path and clubface... but nothing about the ball just sitting there on the hill affects it's spin axis.
What's the static axis tilt of a ball on a 5* slope? Would it be zero as with no slope?
There is no axis tilt on a ball that isn't aleady struck.
Only path and face matter.
If I sit down on the slope and make myself just as tall as I would be if the ball was on a flat plane, then I've just eliminated any effects of the slope.
What the slope does is help you angle the face down or up... just like if I were to change the lie angle of your golf club. Toe down or toe up relative to a 0 plane angle is what we're REALLY talking about. Not axis tilt on the ball. The ball is just a ball with no properties of motion yet until you expell energy into it through the path and face angle.

I am not sure I understand this yet.
On a sidehill lie what does the top vector of the D plane look like relative to a target, say a pin. Is it a line from the top of the pin down through the top of the ball perpendicular to the earth or perpendicular to the sidehill slope?

Situation:Sidehill, ball above your feet. You aim your stance and path at the flag and swing. Impact will have the "bottom" vector of the D Plane straight at the flag and "parallel" to imaginary horizontal ground, and the face angle is pointed left of the flag. Thus the DPlane is tilted "to the left" and ball will draw/hook, with spin axis accordingly.

Think about it this way, whenever the ball is above your feet it's like having a flat lie but you're using an iron with a very upright lie angle. Opposite when it's below your feet.
Thank you Jim, perfectly said.
