Procise does not go into block mode. I can tell you have not watched the videos provided in the 'Video of Pass Interference thread'. Several different camera angles have been provided by people at the game. We have an opposite end zone view which is very clear and represents the position of the judge who called the TD. He had the best view of the play.
In addition, we have a video posted on vines from the back end of the end zone literally yards from the play posted by a fan, which is hi-def. You can clearly tell from both videos that CJ does not initiate contact and has his jersey tugged down (definition of defensive holding) by the DB.
Further,
this video posted by a fan (obviously) diagrams how CJ was not committing offensive PI for three reasons.
a) That the DB initiated contact with is hands FIRST. Therefore, CJ cannot be help responsible for the contact throughout the play.
b) That the DB turned CJ inside with his blocking, which prevented CJ from running a route and clearly shows CJ was not successful at trying to block the DB from making a play (because the DB had no intention of making a play on the actual receiver from the second the ball was snapped).
c) That CJ was tugged downward by the DB who was in fact, holding the WR.
