I believe that the opening crawl was written later by another person (I'm sure someone here can correct me if I have it wrong) so it introduces this little inconsistency. In another topic Centauro suggested that this problem could be fixed by changing it to "Nexus combat team", leaving out the generation, so we could avoid these problems (Deckard/police not familiar with the model that caused the ban etc).
I read that the original reason Roy's team were to be retired was that they had gone rogue, it had nothing to do with Replicants being illegal/banned on Earth.
