In my opinion, whether your data is derived from other data isn't determined by having the same object ID. If I completely remove all tags from a node, move it somewhere else and add new tags, then it's most likely not derived from the previous work. If I add a tag to a road, then it is derived from previous work, and this doesn't change at all if I choose to copy the road and delete the original. Using the object history is just an approximation based on the assumption that mappers will usually keep an object if they are improving existing data, and create new objects if they add completely new information. It's not really possible for an automated process to do anything else.
