My guess is that Google could run this new Panda algorithm at any time, which would effectively lift penalties (or the penalty-like element of Panda) for sites that have been hit.

maybe I am misunderstanding Panda. Or, maybe I am just misunderstanding the statement above.

I thought it was just a (significant) change to the algorithm. I don't understand the concept of it being "run." I believe Matt said that if you made changes to your site, then they would be noticed the next time your site was crawled by googlebot and the index changes would take place as they normally do.

am I missing something here?

(Maybe the quote meant that when Panda 2.2 is released the changes in the algorithm might reverse some of the effects of the prior changes in indexing?)
