About the two voicings

The voicing function applied to the chord set in Scaler3 turns the chords that we worked so hard to make into four-chord chords into three-chord chords. And what confused me was the voicing function in the main track. Why is there this voicing function again? How do people use it? Is a voicing function that applies to an incomplete chord set even necessary?

Doesn’t anyone find it strange that there are two voicings? I don’t understand their role at all, and I think voicings are important in chord progressions.
