The title is quite misleading. This is a tutorial on reading a Lean verification script so the title should be like "Anatomy of a Lean verification script". As it is it suggests that all formal proofs look like this which they typically don't.
The title seems quite apt in my opinion. The article describes a proof as does the title. It doesn’t claim that all proofs are like this. The title isn’t “The anatome of formal proofs” or “all formal proofs” or anything similar.
