Thank you - that is the documentation I was looking at, and it not quite
as explicit as it could be: there is a series of notes including this
one

- Only piece and opus are printed in a \score when the paper variable
print-all-headers is set to ##f (the default). 

which could be supplemented by

- The piece and opus are ignored when in a \header block not inside a
\score block. 

I think at the moment you can only discern that by spotting absences.
