Yes, it is plausible the petition was denied but the information was not updated on USCIS's website. Unfortunately, the information on the website is not always up to date. Your brother and his attorney should have been mailed a copy of the decision. At the very least, his attorney should be able to provide a copy. Your brother can also contact USCIS by phone to verify a denial was issued and request another copy of the decision be sent.
