Same blood really just meant Sasuke, he only said that to further enforce Sasuke into thinking that he only should be the one to fight Itachi. Itachi used Tsukuyomi on Kakashi who had Obito's right eye and according to Obito and Itachi had better prowess and skill with it than most actual Uchiha members. Yet Itachi wanted him to be tortured and not killed or maimed and that's exactly what happened, instantaneous torture that lasted 1 second. I think the clear implication according to Obito's own words is that Sasuke never actually saw through any of Itachi's illusions, Itachi let him break them all including Tsukuyomi all in an effort to not only die, but to exhaust Sasuke's chakra, remove the cursed seal and get rid of Orochimaru from him and Itachi succeeded in all of those. He played Sasuke like a fiddle. So in reality I don't see a completely serious determined to win Itachi using a watered down Tsukuyomi like that in this and Obito will be smart to avoid it because all that would take is literally 1 second.
