Cause Obito knowing itachi, knows that he's really smart and if they were to fight itachi would find a opening in his techinques in a matter of seconds
Which is why Obito didn't wanna risk fighting him, cause he knew there was no limit to Itachi's analyzing skill.
Obito was in a situation, where it was better safe than sorry
And adding on to everything Lilt had said in his thread which also holds true, Itachi could defeat Tobi with the techinques he already has. There would be no need for any new jutsus for Kishi to give Itachi to win.
