I saw an interesting clip of his recently talking about this, and he was basically saying that voices can't be pigeonholed into discrete ranges like "tenor" or "baritone". He has certainly expanded his range beyond what would have been thought possible. To hear him talk, you'd never think "that's a tenor!"
He has done many tenor roles, he was a tenor for quite a long time. He does baritone roles now but still tenor as well. He's been around a very long time, 2001 was his debut.
Sometimes it's just a case of when (what time of day, the age of the singer, when the singer finally "gets it", the singer's intelligence combined with a variety of parameters etc.) the diaphragmatic support is better and the singer's physical energy is at its peak.
