Ortho + orbiting view upwards results in inverted model

Anyone know what’s happening with this?

When in orthographic mode and orbiting the view through the Z axis the model inverts and doesn’t look correct. This doesn’t happen in perspective mode

Well, I figured it out after posting, but definitely try it out for your self:

Basically, it looks like it is inverting, but if you envision the furthest point coming closer and closer it is actually correctly rendering! Gah, my head is inverting!!

See attached blend.
