Whats up with OpenGL winding?

The order in which you indicate vertices determine the clock-wise or anti-clock-wise orientation of that geometry (such as a triangle or a square etc). As you follow that winding see how a right-hand-screw will advance. The direction of the advance will tell you which surface is facing outwards and which surface is facing inwards.
