The first thing that comes to mind is he sees this in posts which are
direct Cc replies to his own posts from some user(s). Thus, what he is
seeing isn't the list post, and something in the poster to list path is
stripping signatures so other list members and the archive don't see it.
(Perhaps the sig is in a MIME part removed by the list's content filtering.)

You need to get a complete, raw message from him with the spurious sig,
all headers, etc. If he uses the gmail/googlemail web client, he can
click the down triangle 'more' button just right of the swooping arrow
'reply' button, click 'Show original' and copy/paste the result. This
will tell you whether the message even came to him via the list and
where in the message parts his sig appears.
