Not sure what to make of that description. Why only 2 watts for the 500-ohm segments?

Assuming a constant current through the resistor, a 500 ohm section will have roughly 1/10 the voltage drop across it as the 5300 ohm section, hence 1/10 the wattage (actually it'll be slightly less than 1/10).
(If the 5300 were 5000, the figures would be exact.)
