Extrapolating what little I know about 2-fret pull-offs, I believe that Draconus is telling you to put four fingers on 4 different frets (5 - 8) then first pull your pinky off fret 8 ("pull off 8 to 7"), then pull ring finger off fret 7, then pull middle finger off fret 6, leaving you with your index finger holding down the string at fret 5. Logically and mechanically, you can only do an effective pull-off by lifting the finger that is furthest up the fretboard.
