More syncopation! On beat two of the first measure, you're grabbing all three notes of the "Rolling E7" voicing at once in a thumb/index/middle finger pinch. The b3 bass note on the third beat of measure two resolving up to the root is a cool way to change things up in the bass without disrupting the flow of the alternating thumb.
