No, the autosupout.rif does not generate one if it the "ping" part of watchdog. The supout.rif is only generated if the hardware watchdog timer expires.Already exist from 2007...
Note: Watchdog reboot is not a system failure. Such reboot also will not generate autosupout file. Watchdog reboot is "/system reboot" automatically triggered by operating system when some service is not responding as fast as it should. Reasons for that can vary between damaged hardware, slow software implementation for some service, DDoS attack, bad configuration and others.
It's quite misleading, especially with the options next to each other in winbox.Right, I never realized that the options were unrelated, even if in the same context, because I never needed it.

And it's a good thing you wrote it because I didn't remember that note... from 2007...
