My sense of how this works is that lifetime status isn't matched, but if your lifetime status is highest, it's matched as an annual status to the other program (although that would really follow as a result of matching annual status from one program to the other). For example, I'm LTPP on MR (from legacy MR LTP long before August 18th) but only LTP (from legacy SPG LTP, also long before August 18th) on Starwood. This part of my status has been showing pretty consistently since not long after August 18th, even though my annual status on the two accounts is still messed up most of the time (although there were days when it was correct).
