ADin channel numbering with PIC16F18854 ?

The 16F18854 family have the ADC pins grouped by port instead of consecutive numbers like older devices. ANA0-7, ANB0-7 etc.
How do the channel numbers for the ADin command tie in with this structure?

I'd guess it follows the ADC channel selection bits as stated in ADPCH<5:0>.

ADin 0 = ANA0 ... ADin 8 = ANB0 ... ADin 23 = ANC7 ... ADin 63 = FVR
