  We show that, contrary to the claim by Kumar [Phys. Rev. A 96, 012332
(2017)], the quantum dual total correlation of an $n$-partite quantum state
cannot be represented as the quantum relative entropy between $n-1$ copies of
the quantum state and the product of $n$ different reduced quantum states for
$n \geq 3$. Specifically, we argue that the latter fails to yield a finite
value for generalized $n$-partite Greenberger-Horne-Zeilinger states.
