Oddly enough, I had the same experience with my Rosco Platypus. The seatpost bolt was very tight to turn, but worked sort of okay for almost a week through a few adjustments due to trying different saddles. Then as I was turning onto my street after a ride, the seatpost slammed down. The bolt still seemed to be tight, but I finally marked it and could see that it wasn't turning in the nut even though the bolt turned with difficulty. Then, as I was suspecting and sort of hoping, the bolt broke. I never found the nut so don't know what was up there, but it sure seemed like the threads slipped enough to jam. I don't know how else the post would suddenly slip and the bolt still feel very tight. It was such a freak thing I didn't mention it, but now I hear of another case.
