At about 02:10:33.6 the PNF said: "According to all three you're going up, so go down". He could have been referring to the two PFD's and the standby instrument, or to attitude, altitude and V/S. Take your pick.
Altitude is the only thing that makes sense.
The PFD method for displaying altitude did not help this crew in altitude awareness. The old counter-pointer altimeter display would have been much more explicit as to what was happening.
