I am seeing the same thing regarding older crap sites, I have several and this update did nothing to them, actually seeing a little more traffic to them.
My older more authority sites took the big hit.. Has nothing to do with quality of the articles, there is another profile these sites fit in that I cannot put my finger on.
Funny that one of my sites that has the same structure, content, link profile and age got a nice boost from this update, when the others took a hit.
Makes no sense what so ever.
