I don't understand your point?
This van was parked in a very dangerous position. Not just making it inconvenient for traffic. But making it dangerous for people to get past on a busy corner.
There is plenty of parking nearby which would be on double yellow lines but not dangerous. I fully appreciate that some classes of vehicles e.g. clampers, ambulances and cash in transit vans should have some leeway.

I presume they are happy to risk getting a fine (which is unlikely I'm guessing), as it makes them safer, and quicker.
There's obviously more to this as a one off parking wouldn't attract someone's scrutiny.
