After review by the development team, it has been determined that this issue is related to a known limitation with the software that lies outside of Esri's control. The issue's Additional Information section may contain further explanation.
When geometries share a border with the clipped features they have to be taken apart and put back together. There is no guarantee that the vertices will be in the same order after that process.
