Particle production by a semitransparent mirror accelerating on trajectories which simulate the Hawking effect was recently discussed in 3. This author points out that some results in 1 are incorrect. We show here that, contrary to statements therein, the main results and conclusions of the last paper remain valid, only Eq. (41) there and some particular implication are not. The misunderstanding actually comes from comparing two very different parameter regions, and from the fact that, in our work, the word statistics was used in an unusual way related to the sign of the {beta}-Bogoliubov coefficient, and not with its ordinary meaning, connected with the number of particles emitted per mode.
