debian/control files: Identical maintainer and uploaders

[Simon Kainz <simon@familiekainz.at>]

Hi!

After grepping around in Sources.gz on my favorite mirror, I found the 
following:



Package:    colo
Maintainer: Martin Michlmayr <tbm@cyrius.com>
Uploaders:  Martin Michlmayr <tbm@cyrius.com>, Peter 'p2' De Schrijver 
<p2@mind.be>


Package:    extra-xdg-menus
Maintainer: Peter Clifton <pcjc2@cam.ac.uk>
Uploaders:  Peter Clifton <pcjc2@cam.ac.uk>, Hamish Moffatt 
<hamish@debian.org>

Package:    openvpn-auth-radius
Maintainer: Cygnus Networks GmbH <debian@cygnusnetworks.de>
Uploaders:  Dr. Torge Szczepanek <debian@cygnusnetworks.de>


So what's the idea in having the same person ("same" in this context 
means same email address) in both Maintainer: and Uploaders: field? Some 
leftovers from someone's transition from DM to DD? Or maybe a workaround 
to fix some issues concerning uploading rights? I'm just curious.

Thanks in advance,

Simon
