So let me understand this. Matt Cutts implies that the past Panda runs (Panda 1, 2, 2.1) were about pushing sites out. Does that mean once you've been Pandalized, you have stayed Pandalized? The whole idea that it's a penalty sounds fitting although I know a lot of folks say it is not. So he admits not to have run the algo to release Pandalized sites yet by "pulling them back"? Past Panda runs were just about finding sites that should be Pandalized. Granted it's a reranking, his use of words is interesting.
So this is just speculation, but I ask: if you were recognized as Panda, any past runs of Panda would not have released you and instead would have either aggravated or eased your situation a little via tweaks. But the stigma is there until you are "pulled back" with new recomputations.
I'm wondering what he means by the terms he's used here.
