Limit to how deep a Many-To-Many will go with CakePHP - cakephp

Question

Is there a limit to how deep a select all will go for a many-to-may relationship? I have a design like this:
Table Survey has many Table Survey Sections. Table Survey Sections have many Questions. Table Questions have many Table Possible Responses.
If I do this for the Survey Table:
$this->loadModel('Survey');
$this->Survey->recursive = 2;
$getSurvey = $this->Survey->find('all');
It will only go as far as the Questions table but bring back the Possible Responses Table. But, if I query the Survey Sections table, it brings everything back. Is this an issue with my code or a limit to how deep a search will go?
Here is my Models:
<?php
App::uses('AppModel', 'Model');
class Survey extends AppModel {
public $validate = array(
);
public $belongsTo = array(
);
public $hasMany = array(
'surveySection' => array(
'className' => 'SurveySection',
'foreignKey' => 'surveys_id',
),
);
}
<?php
App::uses('AppModel', 'Model');
class SurveySection extends AppModel {
public $validate = array(
);
public $belongsTo = array(
);
public $hasMany = array(
'Question' => array(
'className' => 'Question',
'foreignKey' => 'survey_section_id',
),
);
}
<?php
App::uses('AppModel', 'Model');
class Question extends AppModel {
public $validate = array(
);
public $belongsTo = array(
);
public $hasMany = array(
'PossibleResponse' => array(
'className' => 'PossibleResponse',
'foreignKey' => 'questions_id',
),
);
}
<?php
App::uses('AppModel', 'Model');
class PossibleResponse extends AppModel {
public $validate = array(
);
public $belongsTo = array(
);
}

You should use $this->Survey->recursive = 3;.
As I said in the comment, the example at http://book.cakephp.org/2.0/en/models/model-attributes.html#recursive is a bit misleading because it only show an example for a specific case. In fact you can go as far as you want when fetching data.
