Am nothing close to an expert, but.........
RF (AC) impedance and DC resistance are unequal animals. RF impedance cannot be measured with a DC resistance measuring VOM. Despite the heating, your dummy load's impedance may not be changing enough to alter the VSWR greatly.

Hopefully, the experts will be along to correct me and we'll both learn something.
