Views issue: How to pull content from two different taxonomy vocabularies on same page
I tried it myself and views filter OR group is not working.

I think you just hit on a known bug.

Follow the discussion in this issue and this one and apply the latest patches mentioned and see if you can make it work.  Make sure that you post back with your experience (did it work or not) so you can help this issue move along and eventually make it into a release.

As a workaround consider using 1 vocabulary (instead of 2) that holds all terms and your views filtering does not need an OR group.
