What "high temperature" ??

Whether or not the original recirculation passage is functional does not increase the temperature of the water that the thermostat sees. While without recirculation there may very well be hot spots created in the engine block, the thermostat does not sense engine block temperature. In either case, when coolant temp reaches the thermostat rating the water will start to flow to the radiator.

Always open to learning, but I do not see where a thermostat is subjected to any "high temperature" regardless of whether the coolant is or is not recirculated during the warm up period. Thermostat can only get so hot and then it will open.
