That was basically the logic. Rotate the pip mark toward the sun, rather than away from it. It wasn't meant to be precise, but it made a simple reference point.

At the risk of restating the obvious, that only applies to the sky. And the mark is precise.

If one understands polarization and knows what one is doing, one can rotate the mark to the plane of the incident and reflected/scattered ray, or perpendicular to it.  Otherwise, you can simply rotate it according to the appearance that you are trying to achieve.  You don't have to understand it or use it, but it has a purpose.
