The first step down fix is there because there is a substantial hill just to the left of track rising to the height, the second because there is two high rise buildings under the final course. These step down fixes are coded in the FMS as at or above constraints.

The two step down fixes in this case are required because of the obstacles on final, the only other reason for step down fixes is when the final segment is very long an extra vertical splay needs to be applied, using a step down fix in those cases resets the final segment distance.
