Yes, the right side rear axle For LSD equiped cars has the two sets of splines.
The second picture is the LSD differential carrier and ring gear.

Does the LSD differential carrier fit inside the differential?

Technically the differential is inside the differential carrier but your thinking about the outer case that you see under the car that the differential carrier fits into.
