I don't think there is any branching involved. When you place a stone, you add zobrist_table[point][color]. When you remove it, you subtract it. That's all you need to do. If you had a value for empty, you would have to add and subtract zobrist_table[point][color]-zobrist_table[point][empty]. Nothing else changes.
