Why $query = new JDatabaseQuery; but not $query = &new JDatabaseQuery; ?

In ../models/fields/helloworld.php on line 29

If you use the line, $query = new JDatabaseQuery;, component works, but when helloworlds is added as menu item it causes the following error when item is clicked:

Fatal error: Cannot instantiate abstract class JDatabaseQuery in C:\xampp\htdocs\test_site\administrator\components\com_helloworld\models\fields\helloworld.php on line 29

Reverting back to code from part 11, $query = $db->getQuery(true);, does not throw error.

Just an observation.
