The voicings used within this example are not typical outside of this technique although they do have theoretical relevance.
The main thing to note about these voicings is the construction.
It is important to use voicings which utilize all 6 strings when working with this technique.
Yes, it's possible to use voicings with only 5, 4, or 3 strings, but the 6 string voicings create a very nice harmonic depth.
