Stewart is a 31 year old catcher and is arbitration eligible for the first time this off-season. He doesn't do much with the bat, hitting for a career .214/.287/.288 line in 645 career major league at-bats. If the transaction goes through, then this should mean the end of Michael McKenry, who is also arbitration eligible.
CBS Sports released a chart a few days ago listing the best pitch framers in 2013. Stewart ranked number two with 22.7 RAA. That was higher than Yadier Molina (19.8) and Russell Martin (17.9). So while the offense is bad for Stewart, the defense is stronger than what McKenry can provide. Stewart is out of options, which means he will probably get the backup catching job over Tony Sanchez, moving Sanchez to Triple-A to start the 2014 season.
