  Flying mirrors with appropriate trajectories have been recognized as an
analog system that mimics black hole Hawking evaporation and have been widely
investigated. It has recently been suggested that the partner mode of the
analog Hawking radiation emitted from a moving mirror would manifest itself
through a final burst when the mirror executes a sudden stop. Here we argue the
opposite via the partner formula for the moving mirror model. By expanding the
theoretical foundation of the partner formula and augmenting it with numerical
analysis, we demonstrate that the supposed final burst is induced by a shock
that requires the input of external energy, whereas the Hawking radiation
partner mode, which is associated with the zero-point vacuum fluctuations, is
not responsible for the burst.
