As an officer of the company, the public can presume that he has the authority to speak for the company. One question would be whether he was listed as an officer on the company's Secretary of State filings at the time of the pronouncement. Even without that, if they held him out as an officer in letterhead, websites, etc. they likely cannot "undo" his actions. FWIW, "co-founder" is not the title that matters. The title with the word "officer" is the operative one. Officer is a word that has a legal meaning and generally means the person can speak on behalf of the company, regardless of what a parent entity may later say. They entrusted him with the title. It's why you often see the elevation of someone to an "officer" position comes with a whole new round of background checks and interviews.
