I had hoped it was for indicating the ball above or below your feet, or perhaps open or closed clubface as either would be helpful, Thoughts?
Other than the type of surface, it doesn't matter where the ball
is. There used to be a specific version of the game where it did matter
called "Uneven Lies" and the slope of the ground affected shots but that
no longer exists and never affected regular play anyway. I don't think
there is anything to indicate open of closed face either. You just need
to know/figure out that certain types of shots will affect the aim
point. For example flop shots play like an open face so need to aim to the pull side.
