I think that is a very sane assumption.

You may have a situation that a single preimage is used to
produce more than one postimage, but it does not make sense to
say this postimage is produced by doing this to that preimage
and there is another way to produce the same postimage using
something else.

At least, I do not think the diffcore chain is _capable_ of
coming up with such alternatives even if it wanted to ;-).
