No. The server ignores ID values on a create - creation is indicated
by doing a put to api/0.4/node/create rather than api/0.4/node/<id> which
would indicate an update.

The negative ID is I believe used internally by JOSM as an indication
that the node doesn't have an ID yet and needs to be created when the
upload is done.
