That allows for ball movement related possession. Your complaint was of the "dribble dribble" variety i.e. consecutive seconds of a PG pounding the rock, so if Russ was holding onto the ball for 7.9 seconds per game last season (this ballooned to 8.7 seconds in the playoffs), what exactly do you think he was doing in that time?
Its all perception. We assume guards that shoot more dribble less because we as observers feel a long period of possession is more vindicated by a shot than by a pass regardless of the play called, the time of game or shot selection.
