So, i wondered why we had that assumption. Back in 2009/early 2010 when 2.0 came out and the Droid blew away the world this group was full of multi-touch related topics. Dianne Hackborn answered ALL our questions back then, a feat that probably took up all her work time :P. She also explained how pointer ids are handed out by the system.
original message: http://groups.google.com/group/android-developers/msg/2786021d43ae196d quote: "If finger A goes down, then finger B, then finger A is released, you will see pointer #0 going up and the following movements will have only pointer ID #1 (at index 0 because that is the only active pointer). When the next finger goes down, it is given the first available pointer ID (there is no way to know "which" finger this is, so we assume the first available), thus you see a new pointer ID 0 going down." So, the first available pointer id is chosen. That was our assumption as well. There are a few more threads on the group that go into pointer ids and how they are generated. It seems the Xperia breaks this assumption. Would be nice to hear an official word on this.
