I think the description is right,   maybe need other decriptions.
The tshut *polarity* is low in a short period of time when the TSADC 
controller is reset.

In other words,

If T < (setting temperature), the OTP output the High Signal. ------> if the otp out polarity is high, the TSHUT will work.
If T > (setting temperature), the OTP output the Low Signal.
