Not saying its not the case, but this person doesnt get any afghan matches on gedmatch really(and if the person does, the matches wouldnt really be close anyway). And he/she did get an east iranian match(though he/she did get also chitrali/dard match, which is uncommon for everyone not being dard....but then again, it seems random and even west iranians can get indian matches on gedmatch, so its hard to tell), and could just be east iranian even.
EIther this person is partly herati(afghan still, but much more similiar to other east iranians) or just a fully east iranian with higher steppe.
