The specific theory is bogus, but is the general principle completely unthinkable? For instance, some facial features might correlate with hormone exposure during development, which in turn might correlate with brain development and thus character traits. Might not be a very strong correlation, of course, but human brains are exceptional in pattern recognition when it comes to facial features.
