It reads to me like they clearly state: If you were affected by Penguin, and you have (or built) spammy backlinks that violate the G* TOS, use the disavow system as directed.
Yes, but many of us were hit very hard by Penguin, yet did not build spammy backlinks and don't in fact have a spammy backlink profile (in my case, that's been confirmed by a couple of people more knowledgeable about SEO than I am). So do we use the disavow tool?
I think not, because I think Martinibuster nailed it - I had long thought some pages on my Penguinized site were ranking TOO high on a few keywords, for reasons I never understood. Then Penguin came, and they fell to a more reasonable ranking for those phrases.
