Saw IV

If you haven't seen this film, you would just get yourself confused. So watch it before reading this.

What really confused me with this film is at the beginning of the film, the mastermind was getting cut up and finds a tape in his stomach. The detective listens to the tape. Isn't this the same detective who got trapped in the bolt with the mastermind's dead body along with Amanda's dead body and the other 2 dead bodies? So didn't the tape say that there is someone else continuing his work, so how come he didn't know this when someone closed the door on him in the bolt with the dead bodies? Perhaps I am confusing you but this is my thought of mind about this film.
