Corrected for distortion, or merely rotated CCW?

Yup, what he questioned. ^^^^^

So why is the red line in different places? Hardly any sort of reference is it. Sure you're not being fooled by it?
You never tilted your easel when printing? Common technique for correcting converging verticals.

Tilting an easel won't correct an uneven horizon or out-of-plumb vertical structure. All you need to do is rotate the easel (or rotate the negative carrier if the enlarger has that capability).

So that was where I've been going wrong all these years.
