Obviously the OP's set up really looks extreme (and probably wrong IMO), but in general, longer torso's can result in setback seat and or longer stem.
You should never adjust the seat to get a longer TT length. Any fitter will tell you the first thing to do is get the saddle position right based upon your hip, knee, leg and foot position to the pedals. Then you make stem and bar adjustments for reach after that. If that doen't work, you need a different frame.
