Poker odds question: What were the chances of me having A-2 and beating A-K twice is a row?

Assuming both of you were unsuited (Ace and Off not same suit) and you were holding opposite suits (one of you holding Club-Heart, other holding Spade-Diamond, to make the chances for a flush the same)...
Your chance to win the hand pre-flop is 23.82%., or about 1 in 4.2.
To hit it twice in a row, it's 1/4.2 times 1/4.2, or about 1/17.6 (about 5.6%).
So you have about a 5% chance to beat him twice in a row with those hands.
Now, this does not take into account the odds of actually having the exact 2 hands twice in a row.
The chance that you get A-2 again is 8/52 x 4/51, or 32/2652, or 1.2%.
The chance that he gets A-K is the same. 1.2%.
(not including suits)
So the chance that BOTH of you get the same hand twice in a row is 1.2% x 1.2%, or .01%. 1 in 10,000.
Combine that 1 in 10,000 shot with the 1 in 20 shot (5%) of beating him, and you have a 1 in 200,000 of the scenario you described playing out.
Note: This does include the chance that you hit a straight. Actually, he has the same chance to do so. It does NOT take into account that you hit the 2 on the river both times. It would make my brain explode trying to factor that in.
