BPM is deceptive sometimes.
Most dubstep plays 140 but sounds really slow.
In that specific case I think it's how the percussion and backing instrumentals keep pace but the bass "notes" only hit every other beat spacing it out a bit. TV time is doing something every beat, every note making it busy and frantic.
