If A and B both exist, then "touch A B" might set A's time stamp to be earlier than B's, or later than B's, or they might be set to exactly the same time. POSIX doesn't say, and I suspect that for efficiency reasons coreutils's documentation shouldn't say either (except perhaps to say that it doesn't say :-). The same thing is true, in general, for other coreutils applications. For example, "cat A B" might set A's last-access time to be less than B's, or greater than B's, or equal to B's.
