As a matter of fact this is clearly a bug. Watch this:

Regarless of what those "pseudo selectors" selectors are it is clearly the
case that if you ever implement one of them, the method will not work
correctly. However, for any selector which is not implemented the method
will answer nil anyway. So what's the point in the test?! None whatsoever.
