A file in ipfs is stored/addressed by a hash of its content. If you know the hash of the next version and put that in the file, then that hash will affect the hash/address of the file itself. But the hash of the next version depends on the hash of the _next_ next version, and so on out to infinity... and you almost certainly don't know all those hashes, so you can't compute the hash of the next version, so you can't compute the hash of the current version, if it must contain the hash of the next version.
