I re read the manga today but something was telling me if Sasuke had itachi totsuka blade but modify it to his own arsenal of skill similar to his other jutsu he learn in the past .We know totsuka blade allow the user to put their oponent into a world of genjutsu by it stab/slice and then absorb the oponent into the jar where they will be sealed.If Sasuke put a coat over the totsuka blade then the genjutsu effect will be restricted and obito will not be suck into the sword.We also know that the sword of nunoboko is link to Obito body he can morph it into a staff ,spear,DNA another stuff if he wanted.Sasuke perfect susano sword touch Jubito nunoboko which could activated a genjutsu on him from the totsuka blade (temporary)
Jubito started to see illusion of his past after his sword collide with Sasuke sword
