There's one little word missing there: you mean dissipation RATING.
The resistor's dissipation limit is set by the maximum working
temperature, so the dissipation rating - the dissipation that is
available to be used - decreases with temperature.
If the resistor is already at its maximum working temperature, its
dissipation RATING is zero.
Maybe that little extra word doesn't matter, a lot of the time, but you
can't criticize Rich for using "dissipation" in its strictly correct
sense when you're not.
