Assassin vs True Assassin

Nasu-san CHECK!
If it's just Servant vs Servant, then without complaint, True Assassin would have the better chance of victory. Right, Kojirou doesn't have any means of breaking through Zabaniya. But there's more to it. The problem of Zabaniya is that it's not immediate death. If a normal heart gets destroyed by it, then the person dies immediately but the opponents are Servants. And especially against Kojirou, who has a strong spirit alignment, even if his heart is destroyed he still will have some fighting power left in him. Right in the interval after TA uses his Noble Phantasm, Assassin could close the gap and use Tsubame Gaeshi. Which means....it would be a draw since both of them would end up dead...?
