Compared any other Tsukuyomi he has used, this was rather subtle, which is the problem. It almost didn't seem like it to be honest. When kid Sasuke or Kakashi were caught in the Tsukuyomi, they suffered endless torture. The Tsukuyomi used on teenage Sasuke seemed to lack the psychological proportion in part due to the torture and distortion of time. We a fact we know he didn't want to kill Sasuke, so we can assume, based on that and the fact that his Tsukuyomi seemed much weaker than before, that Itachi watered it down. Sasuke would've been dead either way.
