Segmentation terminology to labelmap indices

In the SegmentationCategoryTypeModified-DICOM Master.json file, there are these fields called 3dSlicerIntergerLabel (like below).

I thought these were the unique ID numbers that will be used when exporting a segmentation to a labelmap. but that doesn’t appear to be the case. Without a color table, segmentations seems to be exported simply by assigning a sequential number to segments in the order they are listed in the segmentations hierarchy.

What is the purpose of this field, and more importantly is it somehow possible to export labelmaps consistently if we use terminology, or regardless we will still need a color table for the correct conversion.
