What you see in the photo is only half the story.
For Ultra-longhaul, the standard FCRC (flight crew rest compartment) behind the flight deck is not large enough for 2 pilots to get recuperative crew rest, so the FCRC only has facilities for one pilot. There are further facilities for a second pilot in the BCRC (Bulk crew rest compartment). The BCRC typically has 8 bunks for cabin crew in one compartment, and a seperate compartment has a seat and a bunk for the second pilot - similarly equipped to the FCRC pictured.
The BCRC is so called because it is located where the bulk cargo compartment typically would be located (aft of the Rear cargo compartment, and is accessed by a stairhouse just forward of the rear galley complex.
