I wouldn't worry about it too much. Basically, chord progressions that move by fifth down "flow" particularly well, for lack of a better word. Classical music, jazz, pop songs all use lots of fifths progressions. In hard rock, chord movement by step in a pentatonic scale is just as common, if not more so, than fifths progressions. In more hardcore metal genres, power chord motions by minor second and tritone are more common. What they suggest here is kind of silly and sounds kind of dull actually, just moving by fifth over and over. It happens sometimes, like in the Lionel Ritchie song "Hello", but generally, songs use fifths, thirds, seconds, hmmm, that covers everything, in interesting combinations.
