The -O (not a POSIX one) flag seems incorrectly described in the manual
page.
What it does (from a cursory look at the sources, matching the result
of testing), is simply not displaying a supplementary information
about the directory traversed when going recursive.
It does not output only leaf (filenames not directory). This is only
the "headline": "\ndir:\n" that is not displayed.
Just try:
$ ls -OF
for example (and combine with -R).
What was the intention of the flag? To have an output with just the
names (including directories) without the formatting about the newline
and the dir?
