The article suggests it's because Obama jumped the gun a little and threw him off pace. I also reckon it's partly because SCOTUS judges aren't quite as used to the direct media limelight as Senators, and this is the first time Roberts has executed this public an act. Plus, frankly, Roberts probably wasn't all that enthusiastic about swearing in a Democrat.
