Is it true? Both their ANE comes from CHG & EHG. Sometimes a ratio between 50-85% EHG and the rest CHG. But I challenge that idea with likely another scenario that would be mostly EHG drifted with some AHG rich Farmer ancestry. In a statement I remember that 'Steppe people could really just be EHG + drift'as evident by their large Ancient North Eurasian ancestry.
