"Doesn't work" how?  What does it [not] do that you were expecting?

    A hook function may call `fc -p ...' to switch the history context
    so that the history is saved in a different file from the that in
    the global HISTFILE parameter.  This is handled specially: the
    history context is automatically restored after the processing of
    the history line is finished.

What "handled specially" means here is that pushing the history stack when you are inside the history hook automatically disables writing to the normal history file, regardless of whether you "return 1" or call "fc -P" or anything else. That should probably be made more explicit in the doc, the only thing it's describing is the implicit "fc -pa".

Yes, it sounds like you understand my confusion:

I expected the implicit "fc -pa".

I didn't expect that writing to the normal history file was disabled.
