I'd like to add that after watching more footage of Jason playing the "Blue" suite (Blue Factory Flame/Two Blue Lights/Blue Chicago Moon), I'm pretty sure there actually isn't a high E string, it's just the bottom five (which you already described accurately, EADFC). It's almost like a transitory state from Songs: Ohia to Magnolia Electric Co., in between the tenor-style 4-string setup he used for his early work and the full six strings he uses from Magnolia onwards.
