Well, there is a slight difference. Anakin was able to survive some serious burns just long enough for a medical team to arrive after Obi-Wan had left him for dead. Sion is able to immediately stand up again in a fight, even if his opposite is trying to kill him. That's like Obi-Wan slashing at Anakin, and instead of dropping to the flour with 3 less appendices Anakin happily continues the fight. I cannot see how any
Force power should make one's arms regrow after they have been cut off or something similar.
