You're right; a deleted way using non-deleted nodes is still subject to change of geometry when these nodes are moved. It would probably be (a) difficult and (b) undesirable to return, along with a deleted way, the versions of nodes that were in force at the time the way was deleted. Remember we're not talking about a "time machine" function here (which would also be interesting, but entirely different). There will be cases where this leads to strange results. Assume you have a simple junction of two roads. Now you delete one of them, and it remains deleted for a while. Someone comes along and refines the geometry of the remaining road, moving nodes about and inserting new ones. He might move the former intersection node for a few hundred metres and insert another node in its place (I often have little regard for the original position of a node when refining geometries, I just add a bunch of nodes and then pull them all about to make it look right.) - If someone later views the deleted road, it will have a major dent where the intersection is, because it still uses the old intersection node. The same if I should delete the former intersection node. Restoring the deleted way will show you that deleted node as well, but the information that this node was, at the time, also part of the other way is not restored. These are things that people would have to keep in mind when playing with deleted objects.
