Your odds are off. It's actually around 1 in 8100.

The odds of a double crit are 1 in 100 - 1% chance, 1/100 probability, at 10% crit chance.

The odds of the same bot attacking twice are 1 in 81 - 1/81 probability providing each bot has an equal chance of being selected each time.

Since both have to happen, we multiply the probabilities, getting 1/8100.

It's considerably rare. But it should still not happen by standard game logic.
