  We're not talking about "a correct realloc."  Remember that the book in
question is //Portability and the C Language//.  If you want to assume that
because ANSI C specifies realloc() as you quoted, all implementation of
realloc() you come across specify it in that way, that's your right, but I
doubt such an assumption is portable, which is why Jaeschke gave the
restriction he did.
