I think we can be confident that Google will "Do the right thing" - they aren't blindly following a "Drop Support for versionX when versionCurrent = versionX+2"
I'm reasonably certain by that by "Two Major Versions" they are referring to "Versions that alter how the platform interacts with the Web." - So, as long as FF 5 and FF 6 behave reasonably similarly, they'll be treated as the same major version, and Google will support FF4 and FF5/6.
Or, it may be the case, after some review, that FF4/FF5/FF6 will all be treated as the same major version, and official support on August, 2011 will be for FF3.6 and FF4/5/6. Time will tell.

Well, hopefully. But they've officially announced the dropping of support, so I have to wonder.

That might be. But that makes me wonder about FF. Apparently the changes from 3.5 to 3.6 are more significant than those from 4 to 6. What's the deal with that?
