Ok, you need to detect that count(target) is greater than 1 for an address.

And that's fine. The problem is that you want more than one router to
handle a specific message. The way to do that is to detect in your
conditions that you will need to handle more than one delivery for the
same recipient, handle one of those multiple conditions, and then let
the remaining condition be handled by your existing router. To
paraphrase:
forwarder:
conditon = is set to forwarder?
data = extract the email to forward to
unseen = true if address has more than one match in database
mailboxes:
condition = is set to imap/pop?
data = extract the maildir to deliver to

Correct. And then you use the "unseen" option to tell exim that it
should continue processing routers even though the current one
matched.

Scroll down to "unseen", it's near the end.
Totally untested, but you get the idea:
# Global definition:
DETECT_MULTIPLE=SELECT '1' FROM mail_config WHERE address =
'${quote_mysql:${local_part}@${domain}}'
and then in the first router where it might hit a duplicate:
unseen = ${if >{${lookup mysql{DETECT_MULTIPLE}}} {1} {yes}{no}}
