That's what I think, too. Nonsense.
People could think that they could get a equivalent concentrated element circuit
by just counting pcb line lenght and thus dropping a L here and there.
In the case of several connected current loops this will obviously not work.
There will be problems doing the "large run" and smaller loops and
comparing the L.

There is "inner" Inductance of a wire, ie. that part of the whole
inductance caused by current distribution in the wire only.
This makes sense, but is only a part.
