Shimano M770 Rear Hub

I need to replace the cones in my rear hub. The schematic shown on the Shimano website is a little confusing. It shows the Axle AND gear-side cone as being one piece. If that is the case it seems I would need to order the Axle/cone and non-gearside cone. Can anyone confirm this? Thanks in advance.

If it is this (hb-m770)

Then it looks like the axle and cone are separate.

Yeah, it's not clear whether the right-side cone is separate from the axle.
