If you don't quote, it's not a pull quote, it's a heading or an aside. The example given is a bit of a miss, yes, because the same words appear quoted immediately; normally you'd pull something a little deeper in the text (like from the middle of a paragraph).
I did mention that the pull quote quotes (excerpts) the main article; that's what makes it different from a block quote. Though there may be ellipses, a summary is not a pull quote.
