Dash Charging is slightly different than Quick Charge in the sense that the chip that controls the fast charge process is on the adapter, not on the phone. So basically, what the article meant is that, by using a Dash Charger, they can confirm that the phone has fast charging hardware built in, it's just disabled in the software side. When u use Dash charger on a QC compatible phone, it will run at the max limit Amp that the QC dictates, not at the Amp that the Dash charger can deliver. The results would be the same if you were to use a QC 3.0 compatible charger instead of the Dash Charger.
