When Itachi did that we initially thought it was just a display of his affection to his little brother, but it turns out he implanted the Amaterasu in Sasuke's eyes.

I think the same thing happened here, when Itachi patted Sasuke's head, he transferred or unlocked the Totsuka Blade and Yata Mirror in Sasuke's EMS, Itachi as we know is a long term planner, knowing that it's a dangerous time Sasuke is living in I doubt he would not have given him the sword and the shield to better protect him from the dangers of the war, not to mention that he already trusted Sasuke before he departed to the afterlife. Plus, I doubt Kishimoto would simply let the Totsuka and Yata be disposed of in the plot.
