It was mentioned before, and if you posted to main area, you can notice the difference.
So you are advocating downvoting people because they have acted like the minimal documentation is accurate and haven't read every single post including a single post where a specific bug is mentioned?
If I click "Save and continue" -- should it publish the post?

Yes it published it. And only afterwards the drop-down list with an option "Drafts for XiXiDu" appeared.
ETA #2
This is a bug, don't punish people with downvotes for publishing their unfinished drafts.
People don't expect their draft to be published when they click "Save and continue" if there is a "Submit" button.
