The lane in the video does not appear to be wide enough to safely share with a motor vehicle, especially one as wide as that service van. The cyclist is not only doing the right thing for his safety by holding the lane until it is safe for the motorist to pass, he is also doing a service for all cyclists by training motorists that they sometimes may need to wait behind a cyclist for a few seconds. Which OMG, we all know is such a horrible thing when one is motoring. /sarcasm

All the riders riding/moving far right (left in this case) when it is not safe to share the lane are the ones doing a disservice to all, as they are teaching motorists that they should never ever have to wait behind a cyclist, even when passing may put the cyclist or others at great risk.
