The behaviour you observe is because
org-cycle-set-visibility-according-to-property explicitly ignores all
the VISIBILITY properties in all the descendent headings of a heading
with VISIBILITY property. i.e. VISIBILITY property of Bar is ignored
when its ancestor Foo has VISIBILITY property.

This behaviour is not documented in the manual:

>>    Furthermore, any entries with a ‘VISIBILITY’ property (see *note
>> Properties and Columns::) get their visibility adapted accordingly.
>> Allowed values for this property are ‘folded’, ‘children’, ‘content’,
>> and ‘all’.

I would say that the existing behaviour is a confusing and might be
considered as a bug. However, it may not always be straightforward how
to deal with different combinations of VISIBILITY setting for
ancestor/descendent headings. Consider the following example:

* Foo
:PROPERTIES:
:VISIBILITY: folded
:END:
** Bar
:PROPERTIES:
:VISIBILITY: content
:END:
*** Baz

Foo is supposed to be folded, but it is unclear how to process Bar.
Should Bar's contents be visible? Should it be folded?

Best,
Ihor
