Sorry I wasn't clearer.

The test case is designed to show the inconsistency. Both messages
will print, even though the sense of the conjunction is swapped. In
other words, the first -d fails, causing the message to print. The
second -d succeeds, causing its message to print as well.

If you do it on an ordinary directory, only one message will print.
