I hate to break it to you, but He is - He most definitely is.

describing it the best i can

bar all the strings on the second fret except the low E with your pointer finger
ring and pinky finger on the F# and B like they'd be if you were playing a B5 power chord
low E doesn't get strummed
the notes should be B, F#, B, C#, and F#

I usually play add9 chords like this:

Badd9 = 1 3 5 9 = B D# F# C#
[font="Courier New"]e|----9---- C#
B|----7---- F#
G|----8---- D#
D|----9---- B
