That's how CACM research highlights work. A published paper is invited to be featured as a highlight. The paper is edited somewhat, generally it's made smaller with some details removed. The edited paper will then appear some time later along with a discussion of the paper written by someone not associated with the paper. If the paper is controversial, as this one is, a long time may pass between the original date of publication and the publication of the CACM research highlight.
