Doesn't mean that Obito inherited a summoning contract from Madara. Plus, summoning contracts can't just be expanded like that. That's what i said.

As to the genjutsu part, it takes considerable skill and power to control a biju. Powerful beings can easily rouse their chakra to break a genjutsu. The fact that Obito could do so easily (and later could control 5 biju) is a testament to his strength.

But as i pointed out earlier, Madara was known for summoning Kurama because he actually summoned Kurama. Hashirama doesn't have the means to coerce a Biju, and apparently no other uchiha since either tried or succeeded. It doesn't really mean anything other than that; summoning bigger creatures requires more chakra obviously, and controlling a biju is no small feat. But this statement never meant nor implied that Obito is thus as powerful as Madara.
