I can't dispute that logic...but, right or wrong, when I played it, I treated the first triplet as 1 beat, the 4th chord of the measure as 1 beat, then the next 4 notes: E-G-B-E, as 1 beat, then the last note of the measure: D, as 1 beat. If you look at the attachment that includes the standard notation, I think those four notes are each 1/16th notes. I may be totally confused, but it sounds right to me when I play it this way anyways...
