A face turn is the action showing a shift in alignment from evil to good. The face turn was Luke Harper clotheslining evil cult leader Bray Wyatt and breaking away from his control as he grew tired of Bray's favoritism towards Orton and the physical abuse he suffered for weeks.
To be more specific this is a soft face turn because a storyline has been built up to reach this point. A hard turn would be sudden and to come out of nowhere to surprise the fans.
The face run is what happens after. We're just at the beginning of his face run, which has so far been a match with Orton.
And that is wrestling terminology 101.
