In [10], as an application of results from geometric invariant theory, it is shown that a two-step nilpotent Lie algebra associated with a graph is an Einstein nilradical, if and only if the graph is positive. In this note, we give a more elementary proof of this result using the notion of pre-Einstein derivation and some of its properties developed in [11].
