The Commentary (MA.ii.784) explains this by saying that supposing a Brahmin goes there and dies, his children might consort with slaves, in which case their children would be slaves. In later times, the name Yavanā or Yonā seems to have included all westerners living in India and especially those of Arabian origin (Cv.Trs.ii.87, n.1). Yonaka statues, holding lamps, were among the decorations used by the Sākiyans of Kapilavatthu, the Buddha's family clan in one of their capitals [likely Bamiyan, Afghanistan] (MA.ii.575).
