Seems that doesn't work here.
First I tried to do the usual testing with rsyslog from the archive.
That didn't work

I then recompiled with the new dh-systemd. That didn't really fix the issue,
seem like some state files got out of sync. (we need to investigate that)
I purged and re-installed a recompiled package.
That package showed an interesting behaviour on dpkg -r:
root at pluto:/etc# dpkg -r rsyslog
(Lese Datenbank ... 277049 Dateien und Verzeichnisse sind derzeit installiert.)
Entfernen von rsyslog ...
ln -s '/dev/null' '/etc/systemd/system/multi-user.target.wants/rsyslog.service'
ln -s '/dev/null' '/etc/systemd/system/syslog.service'


As you can see, it masks the symlinks not the actual service. Not surpringly
I then get
root at pluto:/etc# systemctl status rsyslog.service 
rsyslog.service - LSB: enhanced syslogd
   Loaded: loaded (/etc/init.d/rsyslog)
   Active: inactive (dead) since Do 2013-09-19 01:03:13 CEST; 1min 12s ago
 Main PID: 9861 (code=exited, status=0/SUCCESS)
   CGroup: name=systemd:/system/rsyslog.service

Re-opening the bug report, since this needs further work.

Cheers,
Michael
