Again, not sure where you guys are getting any of that from other than your own presumption. I highly doubt MP could tell much about the set lists for any shows he did not attend, other that probably the TA tour and half the set for the I&WAB tour. Yeah, he followed that kind of thing closely while he was in DT. But he hasn't been in the band for 13 years and hasn't had any involvement in set lists for them. Silly to think he would have done the same thing for a band he was not involved with.
Purely a guess on my part, but if I had to guess: I think it's entirely possible that he may have peeked at and somewhat followed the set lists for the first tour for ADTOE because he was in the habit of keeping tabs on DT and with his departure still being relatively fresh, he may have wanted to know what they were playing. For DT12, I doubt he would have followed closely, but may have looked at or heard about some sets either for local shows or festivals, but didn't really know whether or not they were rotating. For TA, with or without looking, I'm sure he knew they were playing the entire album. For I&WAB, hard to say whether he knew the entire set or just the I&W and ACOS parts. Beyond that tour, I doubt he knew anything about sets and any set rotation beyond shows he may have gone to and anything JP may have said to him.
