Default VSWR doesn't matter? But how about "mismatch loss"?

I have quickly calculated that if a
transmitter outputs 100 watts, and the TX antenna has an impedance
that will cause a VSWR of 10:1 -- using lossless transmission line --
that the mismatch loss in this "lossless" system would be 4.81dB!
(Reflected power 66.9 watts, RL -1.74).

Taking this at face value, yes, the "mismatch loss" is 4.8dB.
