That's an assumption, I read it just fine. :) I just disagree with how the author keeps talking about draftsman's lettering as if it were some company's font (e.g. Gorton and Leroy) rather than a commonly taught community standard.

They do later talk about the real origin in 1894 in England, with TT&H creating it due to the constraints of their self-built lettering machine to engrave tiny letters on their products

As I mention in a previous comment [1], this style of hand lettering was common in textbooks prior to 1894. From 1883, for example, we find this specimen in Standard Lettering, published by the Columbia School of Drafting:
