Are we saying then, that some mono recordings are cut in stereo and
that the engineering is such that they can get the balance badly wrong?

In the UK at least, cutting facilities used a separate mono cutter head..
Both EMI and Decca had lathes fitted permanenty with mono cutters
on which replacement masters for mono material, and also mono singles
were cut.

On say a compilation album where some of the tracks were mono and some
stereo, would this still apply? If so how?

These would have to be cut on a stereo lathe. For the mono
material the cut would have only lateral excursion and the cutter
could work at nominal fixed depth.
