Look at example 15 and begin by placing your 2nd finger on the 9(2), 14th fret 6th string. Next place your 1st finger on the 3, 11th fret 5th string. Use your 2nd finger again for the 5, 14th fret 5th string. Finally stretch up with your 4th finger 19th fret 5th string for the root. Take this same layout and move it over to the 4-3 string group. It gets easier on those strings. If your guitar has 24 frets, you can then move it over to the 2-string group. Some guitars may limit access to this stretched out hand position due to the nature of the treble side horn of the body cutaway. This is only a problem if you are going to assign one finger-per-note for the 3, 5 and 1 placement. Using legato slides or alternate fingerings will remove the obstacles of hand and wrist access. Study the video regarding this issue and understand that this 1st inversion one-three form of the Add 9 arpeggio may not be one of your preferred layouts.
