The answer is because dominant chords that are a tritone apart share the same 3rd and 7th. "[6] Patricia Julien says it involves replacing "harmonic root movement of a fifth with stepwise root movements (e.g., G7–C becomes D♭7–C) so that although stepwise root movement is involved, the relationship between the chords is functional".[8].
