I suspect that they added an additional reset path for the Pro/Max variants. On my M1 macOS seems to only use this watchdog to reset the machine. And if I understand the linux reset infrastructure correctly it's still fine to have this as a "fallback" reset notifier even on the Pro/Max and add support for the proper "pmgr" reset notifier eventually with a higher priority.
