Good Sign?? need help to answer

After more than one year, LUD of I485 of both my wife and mine were changed today. But content wasn't changed. Is this meaning that our name check is finished. We were told by CIS and local senator that our cases are under the name check two month ago. Anyone can explain this would be very appreciated. Our PD is March 2003, I140s were approved at May 2004. Our AD of I485 is August 2004. Have done three time FP (code 1, 2 and 1).
