My example assumes a worst case of 0 dB return loss at all harmonic frequencies (i.e., the harmonic energy is all reflected). Any radiation or other loss mechanism at the harmonic frequencies will just decrease their reflected power and lessen their contribution to the total broadband reflected power seen by the meter. The real situation is even more complicated, as the directivity of the wattmeter coupler as a function of frequency must also be taken into account to determine the actual indicated VSWR.
Also, I should have said in the original post "... your antenna would have a VSWR of 1.07 AT THE FUNDAMENTAL FREQUENCY." 73...
