The Lich King's power restored

[Yoda]

After Arthas broke into the Frozen throne, and got possessed by the Lich King, its likely that the Lich King became as strong, if not stronger, then he was before his "powers started draining." Then wouldn't he regain control of Sylvanas, and all the other undead warriors he had had before?

No think of it as a cage. When a person dies he/she becomes trapped in a cage by the Lich King. When the Lich King's power was hurt by Illidan, the cage "opened" and the Future Forsaken escaped from it. The loyal UD tried to save their master because of their thirst for power. When they Lich King regained his power it was too late to "recage" them since they left.
