(< vibhASAGizyoH) won't work after consonant plus v व् m म्.

Or in other words, < vibhASAGizyoH will not work when it would make consonant + (v व् or m म्) + n —

Atman- आत्मन् m + /Gi → !**Atmani आत्मनि, cannot make tmn त्म्न्

Atman- आत्मन् m + /zas OR /Gas OR /Gasi → !**Atmanas आत्मनस्

atharvan- अथर्वन् + /Ge → !**atharvaNe अथर्वणे, cannot make rvN र्व्ण्

parvan पर्वन् + /os → !**parvaNos पर्वणोस्

Why do we say "v व् m म्"?

A sandwitched S ष् is peachy:

**takSan- तक्षन् + /TA
→ takSnA तक्ष्ना by << SapUrvahandh...
→ takSNA तक्ष्णा with /Natvam
→ !**takSNA तक्ष्णा "with carpenter"

**takSan- तक्षन् + /Ge
→ takSNe तक्ष्णे "to carpenter" (by << SapUrvahandh... and /Natvam)

**takSan- तक्षन् + /Gi
→ takSNi तक्ष्णि "about carpenter" (by << SapUrvahandh... and /Natvam)

**takSan- तक्षन् + /Gi
→ takSaNi तक्षणि "about carpenter" (by < vibhASAGizyoH and /Natvam)
