That Rebellion was somehow spiritually/mentally connected to Dante and that Yamato is legendary and ancient sword but it is not truly connected to Vergil in any way.(I know their father gave it to them, but it's possibly found/made a sword that gets "attached" to it's user.)
This seems to be true in every iteration of DMC.
Dante can call Rebellion to him in DMC and can materialize on his back in DmC.(And in both universes it changes as he grows in age and/or power.)
But Vergil and Yamato don't do anything like that, sure he handles it with expert levels of skill and can channel magic through it, but that's about it. Besides, apparently creatures like Dante and Vergil can even channel magic through ordinary weapons.
Even in DMC4, Dante had to throw Yamato in such a way that he could catch it, and so did Vergil in the new DMC4:SE trailer.
