It is correct, if you split a way you end up with two independents objects,
only one of them can keep the same ID, so the other will be a new object.

If you care about this, you can add on the newly created way a tag like
created_from=<id of original way>
I don't know if there is such a tag (maybe with another name or semantic) in
use, but if there is I don't think it is widely used.
To be successful, such a tagging practice would have to be handled
automatically by the editors.
