that's not the problem.
The problem is: sender with milter (or a spammer) sets "X-Spam-Flag: no"
which may cause false positives on any receiving exim/spamassassin 
installation setup in the recommended way. 
(We hat exactly this case in April)

yes - but only on your site, receiving mail.

It makes less sense in a milter-setup, that's correct. 
Assuming you set X-Spam-Flag your own and every time! 
(what happenes if your spamd dies?)
And relying on every MUA/filter taking the last occurrence
of X-Spam-Flag.
That's very vague in my eyes.
