Before revision:  We show here that two non-critical systems exhibit similar behaviors as those used to conclude on criticality, and thus, the experimental observations provided in \mbox{%DIFAUXCMD fontenele .
After revision:  To prove this point, they developed a test (hereafter, "Fontenele test") for criticality, which they indicate to rely on our own theoretical result. However, the results we established do not provide necessary and sufficient conditions for criticality, and thus, the experimental observations provided in \mbox{%DIFAUXCMD fontenele .
