Expression always true

In file moodle/lib/navigationlib.php at line 1592 there is a expression

(($category->type != self::TYPE_CATEGORY) || ($category->type != self::TYPE_MY_CATEGORY)) 

But it is always true:
if $category->type is self::TYPE_CATEGORY then ($category->type != self::TYPE_CATEGORY) is true, so whole expression is true
if $category->type is self::TYPE_MY_CATEGORY then ($category->type != self::TYPE_MY_CATEGORY) is true, so whole expression is true
if $category->type is SOME_ANOTHER_TYPE then ($category->type != self::TYPE_CATEGORY) is true, so whole expression is true

Probably, you should use "&&" operator instead of "||"
