I haven't looked into it at all, and I completely stayed out of Carver's meltdown when it happened, but as I remember it, it reverted him back to Banner when he got mad enough. It didn't take away his anger, it just prevented him from going too far.
In other words, he was potentially nerfed. He wasn't actually effected though.
I could be wrong though, like I said, it's been since the comic came out that I read it. And if that's the case, it's possible he was just trying to prevent his WB self. IE, he gets to the cusp of becoming a Gamma God.
I guess he is talking about here...
