Orochimaru gets up from the snake, taunts at Itachi and gets hit by the blade. He then taunts Itachi some more before realizing he gets sealed. Considering he's sitting atop a giant snake head, there's plenty of mobility in there to begin dodging. He didn't even try, because a sword can't hurt him.

The weapon doesn't seems to harm people(like breaking bones, cuts etc) like a physical sword(like kusanagi) does but rather seals them by sucking in the opponents innards into the sake bottle carried by itachi's susanoo. The Manga clearly contradicts this. It repeatedly hurt beings.

Itachi's in his near death condition would have never been able to seal Orochimaru in his massive 7 headed avatar if this was even remotely true. The like I said before Weapon is most likely similar to the Sage's tool(the sealing pot and urn etc),The only required condition is for the blade to pierce the opponent. We've seen the sword seal two beings of relatively low power compared to the Ten Tails. It's you who is making this huge leap in logic that it can seal anything.

The Juubi Jinchuriki pulled a number of stunts thought impossible, like destroying Edo Tensei. I don't think a sword that sealed two people and hit stationary targets is capable of sealing something like that.

It's a situationally useful blade. There's nothing to suggest it's as godlike as people claim it to be. There's a simple thought process to apply to any claim: if it's so useful, why didn't Itachi spam it? If it's so invincible, why didn't itachi spam it? Why didn't he straight up kill Obito in stead of messing about with Sasuke if he had such power? Because he didn't have such power.
