Yes, Bin Laden was still involved in Al Qaeda's operations

One U.S. intelligence official who asked not to be named said “a peripheral scan of the data suggests that he provided strategic guidance and direction to al Qaeda’s affiliates. We knew he had contact with the affiliates through couriers, but the evidence we have now is that he delivered the strategic direction to many of these groups.”

U.S. intelligence analysts for at least two years have said bin Laden exercised strategic control over al Qaeda and its affiliates. As with most intelligence work, however, there were uncertainties.

The idea that bin Laden was a central figure in the command structure of the several al Qaeda affiliates remains controversial among specialists on al Qaeda…

A U.S. official who asked not to be named said bin Laden gave broad orders to al Qaeda affiliates, such as orders to al Qaeda in the Arabian Peninsula, to attack the continental United States. He also said bin Laden received payments from al Qaeda’s affiliates and approved mergers of affiliates.
