Mission Planner Power Module 2 pin numbering

I am setting up a dual battery monitor system with Mauch PL sensors, powercube, and sensor hub with the alert output going to the cube Battery Monitor 2 for failsafe triggers.
Setup: Cube Blue (RC 4.0.4 rc2)

In Mission Planner 1.3.72 the BATT2_VOLT_PIN parameter description says the value 13 is Pixhawk2_PM2 and then two values later says 13 is CubeOrange_PM2. Is this because the pins are the same? If so, shouldn’t it be condensed like value 2: Pixhawk/Pixracer/Navio2/Pixhawk2_PM1
