I'd not say that it's just a plot armour. The fact that Sasuke (+Obito) was the only Uchiha alive, who could face Itachi's Tsukuyomi and break it, remains. Itachi said it's possible with this condition, and it eventually happened. Unfortunately, we don't know if Obito, the second Uchiha alive aside from Itachi, would be able to do the same thing.
