Justifying calling two entirely different symptom presentations as BPD may be possible by asserting that these presentations share a common etiology or may benefit from being treated the same way. But the DSM isn't generally concerned with etiology, or treatment for that matter...
Very true. This is a big strength of the HiTOP - although right now it doesn't makes any claims about the biological basis of the various dimensions, higher dimensions seem to represent something like the common etiology of lower dimensions. If a biological source can be identified for Internalising, for example, it is very likely involved in both Fear, Eating Pathology, Distress, etc.
