AA vs. KK twice in a row

[usi34]

What is the probability of Player 1 getting KK and Player 2 getting AA two times in a row. I saw this happen yesterday and was wondering. The first time Player 1 raised to 20 (they were sitting next to each other) and player 2 moved in for about 80, Player 1 called and lost. The very next hand player (player 1 rebought for 100) the exact same thing happened.
