The _return_url is stored in a hidden field in the launchpad-form.pt between the request to view the form and submitting the form.
_return_attribute_name and _return_attribute_values are also stored as hidden fields and they are use to check the validity of _return_url.
If _return_url depends on _return_attribute_name, the result of a form submission can invalidate it. If this is the case, _return_attribute_name should be overwritten to return the attribute name to which _return_url depends.
