Leaving in itself is sufficient - be sure to hold on to boarding passes, e-mailed itineraries etc. as proof of departure in case you are questioned on some later attempt to reenter the U.S.
The important thing - if you are departing - is that you are doing so before 180 days or more elapse from the expiration of your I-94 (not a problem for you, as your I-94 would not yet have expired when you leave).
I agree, I would only add that when your I-94 is surrendered, the CBP will record your departure. I'm attaching a link from the CBP for persons who forgot to surrender their I-94 - it provides some information that is relevant to your question. Good luck!
