It is very interesting. Kind of reminds me a little of Density Training.
I kind of like the original version a little better because it's less complicated. The 2.0 version seems better suited to advanced trainees with its varying rest periods and different rep goals every session, a little more complicated than I care for. But I like the overall theme of extending the sets with high percentages of your max. I also completely agree with your assessment of the deadlift, it is better suited to low reps and straight sets. I see the deadlift as more of an overall strength lift, not so much a muscle-building lift used with volume.
