MrT:

They should have focused on more Chorus sounds, or better Phaser sounds for example. 

There are more chorus sounds in the H9 than might meet the eye at first glance. Beside the chorus algorithm, you can also get some interesting chorus / thickening sounds out of MicroPitch and H910/H949.  Listening to that video, I thought he probably had a couple of different effects going. We had a guitarist who played at our booth in NAMM that used a small bit of chorus and a small bit of delay to thicken his guitar sound besides adding distortion and sometimes more obvious effects.
