The thermometer he used likely showed a much lower temperature than what was actually on the die. 5-10 C more are not unlikely. It's hard to measure chip temperatures accurately without an on die thermal diode or special kit. So I would expect that when an external normal thermometer showed 50C it was already operating out of spec.
