you get this nice little chromatic descending sequence happening in the bassline If and only if the chords all stay in the same inversion and the bass line doesn't make leaps. That might be what you want and it is idiomatic in some genres/styles. But it might not be what you want or even what you get from the notation depending on how the musicians interpret the notation.
