Twice in 2 hours...that makes no difference. Each hand is an independent event, assuming the cards have been thoroughly shuffled. The odds of getting pocket A's is something like 220 to 1. The odds of getting pocket A's the next hand are still 220 to 1. It's like flipping a coin. It may come up heads 10 times in a row. But, the odds that it will come up heads on the 11th flip are still 50/50.
