It is very common practice for a company to have a buyback plan active for 12 months. The board can approve buyback up to 10% of the outstanding shares without having to obtain shareholders' approval. Whether they bought shares during the approved period or not they have to announce to the market that the buyback has come to end and they must disclose the number of shares bought during the period. In summary, the company didn't withdraw the buyback or the announcement doesn't reflect their financial position.
