I went for infopass appointment yesterday. The IO was ignorant of laws and terms used at uscis. His reply to most of my queries were "your case is very recent and just wait". The RD for primary applicant is 5/21/07 and derivative's is 9/12/07. The only useful info he gave me was about name check. He said primary applicant's name check is pending and to my surprise he told that derivative's name check was completed the very day of FP.
PD had been current all the time since filing of I/485.
