Sorry to push back on this but I'm a little suspicious.
I found a list of (independent) errata for the 2nd edition [0], presumably because it was used in a class. I see one note about the "Rule 2" for transistors but, to me at least, it looks like the author just forgot a "not" in the sentence.
In general, the errata looks like what would exist for a textbook that was written by a person. It has mistakes, mostly typos but just a quick glance doesn't uncover some fundamental lack of knowledge from the authors part.
I'm no expert in electronics, so I don't have enough confidence to make a statement about the competency of Scherz, but your assessment seems hyperbolic.

It's not in any errata. It's a complete misunderstanding of the problem domain and modelling. I don't like to crap on the authors too hard, but they are both hobbyists on the EE side of things and really shouldn't be writing authoritative material on the matter.
The only way to outline this is to do better which I may do if I ever get the time to do so.
One of the fun things in electronics is when someone builds a small signal amplifier then wonders why the output is lower than calculated with zero understanding of source / load impedances. Because no one taught them about that.
