I'm talking about step 5. The elements just magically migrate to the correct position, whereas in the real algorithm they would be moved individually.


The curly braces with the arrow pointing down are the thing implying the recursive calls on that set of elements until you’re done.


you're describing step 6


It would be clearer if they weren't magically sorted early. Maybe they can improve in a later edition of the instructions.

I think maybe Lego would cut away to show one layer of repetition for example.
