Some one high up in the Administration might have wooped the USICS's ass and said why show the PD as 2002 when there are 98 case still lying around.
Now an example:
USCIS might have looked back and noticed that there are still some couple of 100, 98 cases still around and pushed the PD to reflect the oldest application.
Now once they are done with these cases in a month or two may jump back to 2002.
