How did ENA get into WHG and CHG?

I've seen models showing ENA in WHG and CHG. DOes anybody know how this occured?

check the Laziridis paper on Dzuduana DNA from 2 teeth 26 ka in Georgia, Transcaucasia

Dzudzuana = 72 % pré-WHG + 28 % Basal Eurasian
EHG = 75 % ANE + 25 % WHG
CHG = Dzudzuana + EHG

So ultimately the ENA in WHG and CHG is from EHG? Who got it from the y K2b/P1 guys?
