what does it mean when ETA case number shows "Certified" in iCERT?

My Employer filed H1B for 2015 and told me that I didn’t get selected in Lottery and sent me the rejection letter by end of July but when I query for the ETA/LAC number (that was mentioned in the I129 document) in the
iCERT Portal it shows “Certified” status.

Please advice if everything is ok in this scenario.
