I am watching this lesson:

From 5:47 starts SECTION 2.
I do not get which notes are hit from the beginning of the section 2 till A suspended and A major?
I was thinking about 2nd fret 5th string and 6th open then move to 6th string of the second fret, then 6th string 3rd fret and 6th string 4th fret.
But it sounds really odd. Maybe you can help me to recognize?
