Query: Is there any upper bound on current fluctuation in cross-transport
  beyond linear response regime?   Input and output current fluctuations in stationary cross-transport systems
with two kinds of currents are investigated. In Saryal {\it et al.} [Phys. Rev.
Lett. 127, 190603 (2021)], upper bounds on input and output current
fluctuations are proven in the linear response regime and suggested the
validity beyond the linear response regime. We examine these bounds beyond the
linear response regime and find that these bounds are violated in general
nonequilibrium stationary conditions. We show two examples to demonstrate the
violation. Through these examples, we argue that no upper bound on input and
output current fluctuations exist beyond the linear response regime.
