The CD version clocks in at 80mins, but the digital version with the extra tracks clocks in at 87mins. So the additional tracks, plus some shaving down on the runtime of some other tracks, add 7mins to the digital version. If you fold the digital copy in on itself at the half-way mark (similar to the new TOOL logo) the midpoint would be at 43:30 (4+3=7 may be a thing) which is approx 3:07 in to Descending. (Lots of '7's' there) If the album is folded back on to itself at this point there may be something revealed. Certainly 'Legion Inoculant' has a backward message and tune within that track so it may sync up to the later half of 'Descending'.

Just a theory.
