in theory ,as long as the 2ends connected in the master( A AND B) are the same 2 ends that are connected to the external(drop)cable,then it will work.
however,it is more than likely that it needs to be the white/blue to a and the blue/white to b.
extensions should only require(on a 6 pair cable) to be connected
2 to orange/white
3 to green/white and
5 to white/orange
