It did show up there, however due to local drift (the distance, mutations, bottlenecking, refugia, etc) they developed different alleles and old Baloch became something else, like Mediterranean admixture for example. While in Central Asia new Baloch is still classified and connected to old Baloch. It is a measure of similarities than anything elses, perhaps in relativistic way. In this case Baloch in Steppe is cousin (same common source, more similar alleles?) of Baloch in Iran, but not "old Baloch" in WHGs. They are only two options in this case. Baloch in step might be from recent contact with CHG/Iranian Farmer, or it might be from very ancient common relative. If it was from recent contact we would have seen some Caucasus being transfer too, because CHG and Farmer is very rich in it. We don't, however. So only second option is valid, they did have a common ancestor who gave them Baloch. Judging by distribution of Baloch, it was some sort of Central Asian h-g, and most likely from its expansion after LGM.
Hold on, I am of course talking about the 'green' component in the ADMIXTURE run by Lazaridis. I am not convinced that the 'Baloch' component is all the same. Isn't the latter based on modern populations?
