appnamespace is only tangentially about autoloading. More below.

Let's look at a common directory structure:

application/
configs/
controllers/
forms/
models/
views/
helpers/
scripts/
library/
Application/
...

The following configuration setting:

autoloaderNamespaces[] = "Application"

is telling the autoloader that if it finds a class prefix of
"Application", it should try and load it. Zend_Loader_Autoloader only
looks on the include_path -- which will include your library/ folder,
but not the application/ folder. So, it will see if a matching classfile
exists under library/Application/.

Now, the other configuration setting:

appnamespace = "Application"

is telling Zend_Application that classes under the default module are
using the prefix "Application". Looking again at our structure, we'd see
the following mappings::

application/
Bootstrap.php -> Application_Bootstrap
forms/
Login.php -> Application_Form_Login
models/
User.php -> Application_Model_User
views/
helpers/
LoginForm.php -> Application_View_Helper_LoginForm

If you change the setting to read:

appnamespace = "Zoo"

you need to update all classes under application/ to use the "Zoo"
prefix.
