Basically if you modify one of the configuration files and mess up the formatting it'll cause the infotainment software not to work.
If you don't disable watchdog then when it starts up and isn't working watchdog will have it automatically reboot. Since this isn't a transient issue, but a misconfigured file it'll just keep rebooting making it very difficult to ssh back in and fix the file.
If watchdog is disabled then while the infotainment system won't work it's easy to ssh back in and fix the file.
