Similar to how the M xDrive works, yes, but without the advanced hardware and controls of the ATC13 transfer case. M5 RWD mode benefits from the 'Efficiency Mode' built into the ATC13 design, with demand based oil controls, to reduce churning loses and wear.
One further point with the M5, transfer box oil changes are scheduled at every 5th oil service, ~50,000 miles intervals.
