The South polar coordinate is now turning through the circle of
illumination and away from the Sun which will disappear for the next 6
months at those coordinates.In short,it is an orbital cycle and the
polar day/night cycle under consideration here where daily rotation
and its effects are set aside.

The distance turned by the coordinate from the time it enters the
circle of illumination/when the Sun disappears to the time it exits in
late September and the Sun re-appears defines the orbital traveling
axis around which these polar coordinates turn,In the Northern section
it would appear to be above North-Eastern Alaska.It is treating the
polar coordinates as arbitrary turning points to the central Sun and
ignoring the daily rotation of the planet that defines the North/South
orbital points which cause the Sun to set tomorrow at the South Pole
and rise at the North.
