Net/Gross profile with engine out after take-off

In Australia years ago the end of the net /gross takeoff profile finished at 1,500' above the airfield height/altitude.

This has been changed some time ago to a requirement to ensure the take-off profile can clear all obstacles to Lowest Safe . But Lowest Safe has generally a 1000 ft miss requirement to obsatacles within 25 nms - whereas all the profile requires to the 1,500' is 35 feet for straight out or 50 feet for the curve. Why is this 35' miss requirement not so for the LSALT? What am I missing?
