Its controlled by the user adjustable high temp setting and helps prevent a runaway due to thermostat failure from a voltage spike or short. This tech is now available as a standard in our Herpstat 1 and Herpstat 2 thermostats that will be release feb 3rd. It won't make up for a disloged probe but the new Herpstat 1/2 also have a timeout feature where if the temp goes below your low temp setting for more than 30 minutes it will also disable the output. Again, these options can be configured by the user. This helps cut the cost instead of buying a second thermostat and putting it inline. There will always be some sort of circumstance that can cause all your backup plans to fail but this is a start in the right direction. :)
