Some researchers, who hold the theory that the Katsuraki clan had two family groups, view that it was only Tamada no sukune's family who fell with the serial coup and Ashita no sukune's family survived until the end of the 5th century; however, there is no record that supports this view in the Nihonshoki nor the Kojiki, and it is thought that Ariomi followed the same path as his maternal relative, Prince Oshihano.
葛城氏2系統論を支持する研究者の中には、一連の政変で滅びたのは玉田宿禰系のみであって、葦田宿禰系は5世紀末までしばらく勢力を存続させていたと主張する議論もみられるが、それを示唆するような政治活動が記紀に一切記されていないため、蟻臣などもやはり外戚の押磐皇子と運命をともにしたのではないかと思われる。
