The patent also describes use
of polarizers in order to minimize reflections from the two screens onto each other, which is a clever addition to solve that problem should Apple actually look to build this as a real device.
As you rotate one
of the polarizers, you can see through them clearly when their axes are aligned, barely at all when they are perpendicular and to some extent at other angles.
Most important, the wave (if any) that comes out the other side

I learned that Samsung orients its
polarizer (installed to reduce screen reflectance
of ambient light) at a 45 degree angle so the display is viewable in either portrait or landscape orientation.
