Programming Channel Selection PGEC1/D1 vs PGEC2/D2 PIC32MZ EF

Using the PIC32MZ EF family, datasheet DS60001320G.
The chip has two programming 'channels', PGEC1/PGED1 and PGEC2/PGED2.
Obvious comment: These pins are used for programming.
Section 2.4 of datasheet:
Ensure that the “Communication Channel Select” (i.e., PGECx/PGEDx pins) programmed into the device matches the physical connections for the ICSP to MPLAB® ICD 3 or MPLAB REAL ICE™
So... I have to program the device to set the channel on which to program the device?
Can someone please explain this logic? Chicken or egg, anyone?
