I now also know the reason for it: sbuild-update doesn't use the logger that
sbuild does. So the same function executed by sbuild has a different effect
concerning stderr than when that function is executed by sbuild-update.

Right, everything goes through the logger and thus to stdout and the log file.

I also fixed this in git.

That would still let it be output during sbuild-update. I demoted it even
further to debug level to make sure it doesn't get printed during an
sbuild-update run.

I can see that now.

There is now also a new script /usr/share/doc/sbuild/examples/sbuild-update-all
which you might want to try out in cron.

I fixed this in git and will soon apply that as a patch to sbuild in unstable.
Thanks!
