Unless the sun speeds up as it moves to the outer circle, and slows as it moves to the inner circle. But it does not speed and slow perfectly which is why an analemma (figure eight) is formed. On the globe model spring and fall would cast noon shadows in radically different directions. The annalema is insignificant variation which is why sun dials are normally just left in place once they are set up.
I've seen flat earth models that would cause the same effect due to the suns expanding orbit to the outer circle.
