Why does SpaceX’s historic astronaut flight for NASA have two commanders?

SpaceX’s historic crewed mission to space has … two commanders?

Over the weekend, veteran NASA astronauts Bob Behnken and Doug Hurley made history as they launched into space on a SpaceX Crew Dragon capsule as part of the company’s Demo-2 test flight, the first crewed flight to orbit to launch from the U.S.  since NASA’s space shuttle program ended in 2011. The Demo-2 mission launched from NASA’s Kennedy Space Center in Florida on Saturday (May 30) and reached the International Space Station 19 hours later with a smooth docking.
