While I'm not absolutely certain, looking at one of the OS headers /Library/Developer/CommandLineTools/SDKs/MacOSX.sdk/System/Library/Frameworks/IOKit.framework/Versions/A/Headers/storage/ata/ATASMARTLib.h I don't think macOS supports any immediate offline tests other than short and long (in particular, not selective ranges), so I think smartmontools on macOS is simply recognizing that - it runs on a lot of platforms, and not all of them necessarily support every feature. macOS AFAIK doesn't support SMART at all on USB or Firewire; and at least one other OS doesn't seem to fully support SMART for ATA, for example.
