Two different systems entirely.
The white balls on their costumes are the beacons for the black trax system, it allows normal rigged lighting fixtures to act as spot lights, eliminates the needs for actual follow spot operators being hoisted up.
They were also used for the "Seeker" HFO drones tracking in the Arena shows as they were completely automated.
The kinetics were used for several songs during the Arena tour, UD, Globalist, Handler, I'm probably missing something. It's just an input for live visual generation & tracking.
On topic...The setlist seemed decent enough, I don't think the performance was bad, I just don't think they are the same band that people keep thinking of 10-15 years ago, they are in their 30's after all. In terms of the BBC stream, I've seen them enough times to know their live sound, the mixing was awful.
