Found it thanks

Why did they burry what’s arguably the most important piece of information at the very end though ?

I’m not seeing this editor’s note (at least on mobile). Where is it ?

Well it’s in the name, they are code smells, not hard rules.

Regarding the specific example you cited, I think that with practice it becomes gradually more natural to write reusable functions and methods on the first iteration, removing the need for later DRY-related refactorings.

PS : I love how your quote for the Rule of Three is getting syntax highlighted xD (You can use markdown quotes by starting quoted lines with > )
