That's very interesting, suggy. Google has long measured and assigned "query intention" taxonomies - and they adjust them on a regular basis to match up with page-type taxonomies - pure and mixed taxonomy matches are both possible. Any correlation of ta queery taxonomy change with Panda Updates would be quite a new observation.
You saw this phenomenon in exact coincidence with the Panda Update dates?
