EVE supports this etymology and argues that the meaning "south, southener" is a parallel development from the Indo-Aryan endonym through the meaning "a people living south
According to this the term for slave developed from proto-Indo-European *Óryos. The term for southerner developed from Proto-Indo-Iranian (or Indo-Aryan as it states) *Aryas.
It doesn’t make sense for the term to develop from Proto-Indo-Iranian which is usually associated with the Sintashta - Andronovo cultures. The Sintashta are known, for example, for assimilating the neighbouring BMAC culture.
