Specific to a SDS100 belt clip this might work for other manufactures. Link is to the Panduit product I used.
The purpose is to have a surface the finger does not easily slip off when pinching the clip. I didn't use it much because of the difficult of using the clip and only used it to secure in the car or radio carry bag. Originally used without trimming one side. If top edge of anchor was flush with the clips top edge mounting surface there was slight interference with button on radio during removal. Trimmed anchor to allow it to sit higher and no interference now.
For me it makes the clip easier to use for my intended purpose.
