Can these updates really be discussed separately? Most people have no idea which update has hit them.
I think they can and should. If you have an EMD or PMD and your site dropped in the rankings for terms that are also in the domain, you likely got hit by the EMD update.
If you dropped for all terms or don't have an EMD or PMD that matches the queries you care about, you probably got hit by the Panda algo tweak.
You need to do some digging and deduction to figure out which one more likely affected you but if the algo updates are unrealted to each other it makes sense to talk about them separately.
