"Boom..."
It was not that Uchiha Yue's perception was lacking; the Third Hokage's attack had simply caught him off guard.
Even with his Sharingan and Purple Eye observing the Third Hokage's movements, Uchiha Yue had not seen how the Third Hokage formed his hand seals. Then, in the next instant, the Third Hokage used the Summoning Technique right before him. After the old ape, Enma, sent him flying toward Doomsday Forest, Uchiha Yue finally understood the trick the Third Hokage had used earlier.
It turned out that the Third Hokage had begun secretly forming hand seals the moment Uchiha Yue cut down the Hokage Office. At the time, however, Uchiha Yue had been more focused on the destruction of the Hokage Office than on the Third Hokage. Thus, after secretly completing his seals, the Third Hokage came directly before Uchiha Yue and used the Summoning Technique. Relying on Enma's strength, he sent Uchiha Yue flying heavily toward Doomsday Forest.

Yet, just as the Third Hokage had expected, Uchiha Yue did not want to involve too many people in Konoha. He willingly endured all of Enma's force and flew into Doomsday Forest, intending to fight the Third Hokage there instead. Then, once Uchiha Yue planted a heavy foot before Doomsday Forest, the Third Hokage and Enma appeared before him as well.
However, when Enma noticed that Uchiha Yue looked somewhat like Uchiha Madara, even the battle-hardened old ape narrowed his eyes in shock and said to the Third Hokage beside him, "Sarutobi, could the person you're fighting be Uchiha Madara? No... that's impossible. I remember that old fellow Uchiha Madara died long ago, didn't he? So the one you're fighting now
