Hi @michael.wesley,
I know it is confusing! I am going to piggy-back off of @mwood’s answer HERE. When you think about it from the television/screen point of view and the fact a program is read from top to bottom, it makes a little more sense. Python’s Pygame library also uses the same coordinates in that 0,0 is in upper left (see here and here).
Hope that helps a little,
Michelle
