Why assume the entire organization is involved; it could be one person.
Suppose (for argument's sake) that Snowden were depressed or had got cold feet, and was uncommunicative or otherwise climbing down from his previous position; a supporter who thought he was simply undergoing a crisis of confidence might decide to draft a statement 'in the spirit of his actions.'
I'm not saying that this has happened here, but such things are not unprecedented. You don't need to believe that the entire organization is engaged in a deception, or even that the (imaginary) author of such a statement would consider it deceptive, but rather reflective of a 'deeper truth'.
