In this passage, Paul refers to the god Apollo. Satan in the Bible is Dionysus, just look at how he has always been represented with satyr horns and goat hooves (like Pan), red (to symbolize lust and sex), related to fire (the Promethean and warlike aspect of Dionysus), to hell (an aspect related to the god Hades, because Dionysus is also that god), and to darkness (a chaotic aspect), also represented with a tail (as if the devil were also part reptile or snake). But Paul says that Dionysus also disguises himself as Apollo (light). As if there were no dichotomy between them, and that in fact Apollo is also Dionysus.
