I saw this too. Some pages are unaffected. Like nothing has happened at all.
I observed this too (and I may have posted this similar observation on the same thread the OP referred to)...
I have a page on my Pandalized site, linked from the top nav, and monetized at the time of Panda with an affiliate link (just like other pages in the top nav that dropped positions), but this one monetized page escaped. I can't figure out why. Well I have some ideas (below).
My main 2-word phrase that my homepage ranked on for years in the top 15, fell 500 positions; but my unpandalized page ranks in the top 100 for that phrase and it is in the top 10 for longertails that utilize that phrase. This has baffled me. The ONLY factor I can find is that this unaffected page was linked more frequently IN CONTEXT throughout my site -- not just from the homepage or the top nav. In fact, while this page is linked from the top nav of all pages, it is linked only ONCE from the homepage; whereas my three hard-hit pages are linked 4 to 6 times on the homepage, with different anchor text and very rarely linked in context on deeper pages (I don't know why I did that, but it was definitely poor linkage on my part when I posted my articles).
I THINK there is definitely some phrase-based (almost OOP type) scoring in place. The words that were hardest hit for my homepage rankings are all contained within the anchor text of those hard-hit internal pages. I hope this makes sense... I will edit once I am outside this little reply box :)
Some of mine escaped too - they have a stronger backlinks profile
Oddly enough, my unaffected page has a small backlink profile, but it has a couple of E-How links (which are nofollow). Maybe those have helped? I still think it mostly comes down to excessive linking from the homepage with multiple anchor text coupled, and little to no linkage (contextually) throughout the site.
