Unlikely gammon

Just for amusement...
I was playing XG. In the position below, I played 22/21 9/5, and
then XG proceeded to win a gammon, *without ever hitting*. Over
the course of the next 11 rolls, I rolled a total of 61 pips (so
about 5.5 pips per roll). Meanwhile, over the next 9 rolls, XG
rolled 109 pips, averaging about 12 pips per roll.
The bot info below suggests that a gammon win for O is not all
that unlikely (around 3%), but I suspect that most of those
gammons involve some hitting at some point.
