Red John could be Patrick Jane's alter ego in disguise. Lisbon, or Lorelei, or anyone would never know it. The 2005 Tamil Movie "Anniyan" was shot in the same way. Hero has Multiple personality and the innocent Identity assist police in finding the Criminal Identity.
A human's subconscious mind is ahead of him, Just like RJ is ahead of PJ. Processing the wrong list is intentional so Lisbon will be focused on within CBI and Patrick Jane can still continue his disguise. He may have killed his wife and daughter, and used CBI to turn the case's direction. We all know he is capable of it. Truth can only be revealed by shooting a video of PJ's alter ego.
