I haven't tested this myself, but according to the tests in http://stackoverflow.com/a/3017722, the two statements are equivalent. I'd only assume that to be so since it's the logical thing to do and PHP tends to be logical. In fact, if you had two objects $a and $b with the same class or parent class $a instanceof $b would still return true, which is rather peculiar. Regardless, the patch should still work. Cheers!
