Actually, that anomaly holds true with any dice pool in Storyteller where
you have an even number of dice and gain one more (so it's now odd). It
doesn't happen in the example you mention since MORE THAN HALF of the dice
must be ones, so with 2 dice, they both have to be one's which is less
likely than one one on one die. However, 2 dice need 2 ones to botch, and
three dice need 2 ones to botch, so this means that there is actually more
chance of botching with three than two. The same holds true with 4/5 dice
and 6/7 dice and so on.
