Precisely. Unless this revelatory concept somehow makes it necessary to change the way we design systems using these tables, I really don't care if the power flows inside or outside the wires. It is just a mathematical abstraction, anyway.The tables you mentioned are for considering the practical implications of conductors in the real world having a resistance that generates heat, how to size the conductors for mitigating the temperature generated due to this heat, and for how to size the conductors to mitigate the parasitic loss of voltage due to generating this heat.
