請教xiaobaitu等高手：485 notice

EB1 (based on L1-A) case), PD 12/2004, 140/EAD/AP 都早已approve了，一直在等485,通過律師詢問過，11月7日受到書麵回複，被告知case delay, 在background check,可是今天上網發現同一天（11月7日）有個LUD, online case status是：
“Current Status: Fingerprints review completed. Review of the fingerprints taken relating to this I485 APPLICATION has been completed. Processing of this case continues. We will notify you by mail when we make a decision or if we need something from you...."

請問，這個note是說明background check結束了嗎？為什麽同一天的答複會不同呢？請問見過類似case嗎？
