As far as I can see, no, they did not.
As their solution to iTunes integration allows playback DRM iTunes AAC tracks (not video yet though) which XBMCs solution does not (currently). Elan (of Plex) has said he will blog about 'how' they did it soon.
I use XBMC on my Xbox, and Plex on my iMac. Both are great. XBMC has had a massive impact on my lifestyle, I reckon I watch 85%+ less TV as a direct result of me installing this software on my Xbox which sits under the television. (advertisers will be happy!!

).
But as a Mac user Plex is really becoming more and more appealing as they introduce these Mac specific features. Proper sleep, simplified settings, TV Themes (sounds gimmicky but very cool), 'proper' iTunes and iPhoto integration, Ability to launch apps from within the Media Centre (e.g Front Row if you want to play an iTunes DRM'd video) and my favourite integrated updating.
This in addition to other things, see
http://elan.plexapp.com/ for a full list of the recent Plex/Seven features.
I have no affiliation with either team, however, if you own a Mac it is worth checking the XBMC fork of Plex just for the tighter OS X integration. Is there any reason you don't just use Plex freddyflinty?
