what does that mean of 2nd fingerprint?

I submitted I485 (EB-2, priority date 2004,June) in March 2007 and did the first fingerprint (code 3)in April 2007. Today, I got the ASC notice for the 2nd fingerprint for code 2 again. I know that people usually has to do the 2nd fingerpringt 15 month after the first one. But in my case, it was just 11 months since my first fingerprint.Ddoes that mean anything good happened for my I485?

Thank you.
