oop - Accessing private from static method in PHP

Why this works? I mean, accessing the private variable.

class Test {
    private $q = 0;
    public function __construct() {
        $this->q = 1;
    }
    public static function EpicConstruct() {
        $test = new self();
        $test->q = 2;
        return $test;
    }
}

$test = Test::EpicConstruct();

Answer

Because you are accessing the member in the correct context, namely: the class that defines the private member.
