Itachi told a lot of lies, but his words weren't entirely false. Madara seemed to be the first recorded case of awakening the MS, so yeah, for Itachi he was very well the first person to awaken it, so it's not like he lied, he based his words only on the info he knew. The same way, he has always identified Tobi as Madara, which wasn't true, but again, Itachi didn't know that. And the test of power story was Itachi's personal drama, of course, he lied.
