The information on your personal page is fully correct. Those members being non-gold, were not expected to be reset. In fact, for you the previously explained "sliding window" counter comes into play. However, after you once receive Gold, you will be reset to zero and become a "static window" of 12 month for requalification.
Obviously, this mechanism has not yet been correctly implemented in their software, since gold tiers should have experienced that on Dec 31, 2009.
