IMHO it asks for an answer Yes/No. So it thinks this is an interactiv session allthough it is run in the batch.
It seems that it tells you that the updater itself is involved in the update. Thus it will run this first and it tries to tell you that is has to run a second time to do the normal updates after that.

You better run this at least once interactive (e.g. by using YaST), to get past this answer.
