The microscopic origin of the recently observed helical structure in LiCu2O2[1] is considered. It is shown that the frustrated antiferromagnetic doublechain scenario adopted in Ref.1 is unrealistic. It should be replaced by afrustrated single-chain (CuO2) scenario proposed in Ref. 2 with ferromagneticnearest neighbor and antiferromagnetic next nearest neighbor exchange integrals\. [1] T.
