The phrase "None-dissipative resistance" is utter nonsence.

It is my understanding that if the reactance of the characteristic impedance
of a transmission line is zero, the characteristic impedance is non-dissipative
and a pure resistance.

The IEEE's "resistance = real part of impedance" is indeed often non-dissipative.
If a voltage is in phase with a current, the V/I ratio is a resistance but not
necessarily dissipative. That's why the IEEE has two definitions of "resistance".
