And yet the SSDF has had matches start out that way which went to the other
opponent in the end (or something fairly close to that -- I forget the exact
figures for an O-fer reversal).

With chess, the odds of 0/10 for evenly matched chess engines is harder to
figure, but with a coin toss it is easy:

1/(2^10){all heads} + 1/(2^10){all tails} = 1/(2^9) = .2%

Hence, if you had one thousand people flip ten pennies, (on average) two of them
would get either all heads or all tails.  The question is -- are you one of
those people when you run an experiment?

Improbable events do happen.  That's why we buy fire insurance.
