You shouldn't be concerned with either one.

Power dissipation is the rate at which the resistor is converting
electrical to thermal energy in joules per unit of time. When the
periodicity is small compared to the thermal time constant of the heat
sink, then you can you can use the average value of joule dissipation per
cycle, because much like a low pass filter, the heat sink temperature will
not respond to the high frequency component of the thermal dissipation
profile, it will only respond to its DC value, and another way of saying
'DC value' is 'average'. You might notice that computing average power
dissipation per cycle is the exact same thing as computing RMS current and
multiplying by R. Forget about the formulas and consider what it is you
really want to know.
