 The problem is that if the pronoun is to have its descriptive content recovered from previous discourse, the pronoun ‘He’ is going to stand proxy for a description like ‘the man who fell in front of the train’ or ‘a man who fell in front of the train’. Here, considerations about uniqueness implications are of little help. One possibility, advocated by Davies (1981) and Ludlow and Neale (1991) is to say that speaker B is engaged in a kind of pretense—playing along with speaker A, as if saying with scare quotes something like B′.
