As the article acknowledges at the end, this is sort of like protothreads which has been around for ages. The article's CSS was so awful that I didn't read anything except the last paragraph, which seemed to tell me what I wanted to know.

Right, this is more or less this blog author’s riff on (PuTTY author) Simon Tatham’s old page on coroutines using switch[1], which itself indicates that Tom Duff thought of this (which makes sense, it’s only a half-step away from Duff’s device) and described it as “revolting”. So in this sense the idea predates the standardization of C.
