OK, if the following is not the reason, then I don't know anything anymore :)

My playouts allow multiple suicide. I believe Orego does the same. I found that not checking for that actually made things faster overall. But I bet that accounts for the longer average game-length.

If suicide is not allowed I'd say that criteria #2:

  2. In the play-out phase, the moves must be chosen in a "uniformly
     random" way between legal moves that do not fill 1 point eyes and
     obey the simple-ko restriction.

should explicitly make mention of suicide not being allowed.

This is still something I don't understand. Are there others who implemented
the same thing and got 111 moves per game on average? I tried to look
through some posts on this list but didn't see any other numbers published.

111 matches my recollection from past experiments that I did with
playouts that probably match Don's.  I think that this number has been
posted previously on the mailing list.
