If Potlatch is in live mode then each change is uploaded as it is
made so just being in the same changeset does not mean it was uploaded
at the same time.

The history appears to be that, all in one changeset (which is not
necessarily one upload with Potlatch) the node is created, then added
to the way, and then deleted (but not removed from the way).

As I said, this is not something that can be checked at the database 
level. The API should catch it though so if it doesn't then that is a bug.
