The Short Answer
They give off the appearance that they are keeping them but really the leaves are fully abscised, that is, the plant has cut off all nutrients from the leaf by walling it off. The only reason why it stays attached to the tree is because of the connective tissue in between the dead leaf and the tree is thicker in those species than others. When the tree flushes out in the spring the new leaves will knock off the old ones or the dead portions of the connective tissue between the leaf and the tree will weaken enough by weathering for the leaves to fall off.
