This is because "save", "unseen" or not, doesn't save the message at
that point, but rather sets up an additional delivery to be done in the
normal Exim pipeline, ie. at the routing stage.

What I would do (and I think this is the officially approved way) is use
"add" to change one of the user variables, n0 through n9, as a way of
setting a flag; later, at the transport stage, you can test the flag by
expanding $sn0 (for example) and add the header at that time, if indicated.
