Where is your "right" translation? Even if he didn't meet them while they were alive, he still traveled through time as chakra, like Obito did. Obito spoke with and entered Kakashis body, who was still perfectly alive. So on the verge of death, speaking with someone should be even easier.

Again, these are also special circumstances. The 10 Tails and Infinite Tsukuyomi were a threat to the world again. Even if the Senju and Uchiha killed each other off, there was still opportunity for peace in the world through other people. With Madara on the scene there would have been no people anymore.
