Why would they ? They have four runways to choose from that are basically parallel. Plenty of capacity. It's probably the least busy of all class B I'd imagine.
It's actually a ridiculously busy class B airport at certain times of the day.
Also, I *think* 4L was closed at the time this happened so they would have been down to just 8L for arrivals and 8R for departures if he'd put it down on 4R. Not the end of the world, but it would have slowed stuff down. That said, still not a reason to go swimming in my book.
