I think it's particularly interesting (and encouraging) that he says that if you modify your site such that you are no longer tripping the filter, you should go back to being ranked normally according to your relevance.
Of course, if you are filtered by the Algo, then you will probably not know any time soon which of the "over 200 criteria" is deciding that you should be filtered. You could do a lot of damage to your site trying to "fix" things that didn't need any fixing.
While if you receive a manual penalty, you will probably have a pretty good idea of what triggered the penalty, and will have an easy "trial and error" way to fix it through the re-inclusion request.
