Many thanks to bob jenkins, Bfair, and Carl Childress for responding in such detail to my question. This play is finally becoming clear to me, though I did not know that the various organizations specified such differences depending on the actions of the runner after the ball becomes dead.
However, I'm still trying to understand what the FED book is describing in 8.3.5.b: "When a runner who is returning to touch a base after a batted ball has been caught is prevented from doing so because a thrown live ball has become dead . . . his [2-base] award shall be from the base he occupied at the time of the pitch." That would seem to describe the runner in their case play 8.2.5, who was trying to return to first but was prevented from doing so because the ball became dead while he was still between 2d and 3d. In their casebook ruling, the runner is out on appeal because, even though he was returning, he was "on or beyond a succeeding base when the ball became dead." So how can he get a 2-base award when he isn't allowed to return to 1st? Or am I interpreting their words incorrectly?

This is a great web site.
