Ok gotcha!

Those chords starting with the 6th fret then the 9th fret are still an A chord. They are both A triads (different inversions) and we are just moving up the neck to create excitement.

So the slide to the 6th fret is on the G string, and you will arpeggiate the 5th fret of the E then B strings. This spells the first inversion of an A chord. The 6th fret on the G string is the C# note, which is the major third of an A chord.

Next there is the slide to the 9th fret on the G string then arpeggiations on the 9th fret of the E string and 10th fret of the B string. That is also an A triad (second inversion), it just starts on a different note (in this case, the E note which is the 5th of the chord).

There are also some ghost notes that are a quick pick of the open G string before you do the slide to the 6th fret, then also the 9th fret. This should give you a bit of time to get your fingers ready to fret each new shape.

Make sense? Let me know!
