It means an identical position packet is heard.  The D7 and D700 still display new information on the screen if the position of the remote station changes.  It certainly does on mine.  If I'm driving around, I hear lots of stations.  Those that aren't moving show up on my screen as dP's.  Those that are moving show up on the screen as nP's and the new data.

Perhaps there was a small firmware change between a few versions of the radios but I know for sure that on both my D7 and D700 I don't get dP reports if the station moves, I get nP reports.
