GW, you've actually misquoted the meaning of QUJ - or CAP413 does.
It's precise meaning is
QUJ
Question form:-
Will you indicate the TRUE track to reach you (or ...)?
Answer form:-
The TRUE track to reach me (or ...) is ... degrees at ... hours.
- nothing about heading or wind drift. I suspect that CAP413 is trying to explain it and, in the process, obscuring matters. Doncha love civil servants?
