There is a hammer-on from B (4th fret) to C (5th fret) on the G string, then a position slide from the C5 (5th fret) to the D5 (7th fret).  Lee plays it & teaches it correctly, but the notation does not indicate either of these.

Sorry for the confusion!  I'll forward this to the notation team to see about getting it corrected.  Thanks for the heads up!
