It's quite common for corporate boards to be comprised of outsiders, with the CEO as the only board member who is also an employee. I wouldn't call it unusual that Sandberg is not currently on the board, nor is it unusual that she is now joining the board. For example, Oracle has four employees on the board, Microsoft has only one (Ballmer), and Apple has only one (Cook).
