I think that can come in handy in a business-to-business situation. For example, if you have two engineers you can either call them each a "Software Developer" or you can have a "VP of Engineering" and a "CTO".
Now when your customer, Huge-Corp(TM), who is going to pay the bills for the next 3 months calls, would you rather tell them "let me put one of our developers on the phone" or "let me put our vice president of engineering on the phone"?
