Hmm, that's strange... I'm not seeing it. The way Google rolls out tests and betas though there is never any way of knowing if you might be in a test group seeing something different from other people. Many times I've seen random features pop up and then disappear. (I assume because Google was testing something with a subset of people.) In one case I even received an email from Google telling me I was in a private beta of a new feature that I was not supposed to tell other people about it. I'm still pretty proud of that actually.
