  J. An (2013) proved that for any $s,t \geq 0$ such that $s + t = 1$,
$\mathbf{Bad}(s,t)$ is $(34\sqrt 2)^{-1}$-winning for Schmidt's game. We show
that using the main lemma from An's paper one can derive a stronger result,
namely that $\mathbf{Bad}(s,t)$ is hyperplane absolute winning in the sense of
Broderick, Fishman, Kleinbock, Reich, and Weiss (2012). As a consequence one
can deduce the full dimension of $\mathbf{Bad}(s,t)$ intersected with certain
fractals.
