I suspect that someone was going to catch a rocket and a decision was made to place responsibility where it belonged.
the captain occupying the right hand seat (although not licensed as an instructor) was pilot monitoring. Following the balked landing the crew engaged the autopilot, and while the autopilot was active, swapped their seats, the captain returning into the left hand seat, the first officer into the right hand seat, both leaving their seats at the same time. In addition, the captain was required to wear far vision correction according to his medical, but did not wear his vision correction.
