OES 2018 64 Bit ZID and AFP Mapping Confused

According to OES 2018 Documentation NSS Pools / Volumes are created as 64 Bit.

Documentation also states:

IMPORTANT:When the NSS volume is mapped through AFP, the NSS files and folders with ZIDs greater than 32-bit are not listed because of Apple Filing Protocol (AFP) limitation. If the NSS volume is shared over AFP, we recommend not to enable the 64-bit ZID option.

Does this mean that the OES 2018 Pools are 64 Bit, but when carving out an NSS Volume there's a choice to create the volume as 32 Bit vs 64 Bit?
