Whether it is a recton or not it's yet to be demonstrated as the actual Railgun arc occurs before Academy City Invasion arc so something could happen that would explain that part. The best chance for Kamachi to do that was Daihaseisai arc though, as for a reason or another Uiharu's memories about Mikoto could have been permanently modified due to Mental Out (Misaki's or Gensei's).
