I cannot replicate this. When I move the headlines, they remain folded.

Yes, this is a bug. Thanks for reporting it. 

It was introduced with commit 383802d063a9f2dd959d5574b226fa8ec7f8be41,
which caused the problem it intended to solve. See:

http://thread.gmane.org/gmane.emacs.orgmode/28159/focus=28442

The commit has org-mode process the headlines from bottom to top, which
means that any changes to the visibility of lower headlines are
overridden/modified by changes higher up. Reverting the change causes
VISIBILITY to work correctly.

I send a patch shortly.

Thanks,
Matt
