Do I follow that action correctly: the cutting tool is tracing out an
internal hex path by spinning axially and wobbling at the same time?

And pushing the wall material down into the bottom of the hole. You
can always tell a wobble broached hole, as it generally has a star of
material at the bottom. Cold headers tend to compress the material
so it doesnt show the star.
