Seems like Lynch is making things up again.

Sounds like it to me. IIRC, only two of the several CFIs from whom I have taken
reviews in tailwheel aircraft actually had the tailwheel signoff. It was simply
made clear to me by the others that they could not serve as PIC and I was not to
think that they were PIC on the flight. The FAR that Lynch quotes requires a
"qualified instructor", not that the instructor be a qualified PIC.
