I guess Uri was trying to suggest that the second position was somehow
unstable, with white and black both equally likely to win but a draw
being relatively unlikely.  I guess such a situation might occur in a wild
tactical position.  In this case, the 3 probabilities might describe the
position better than a single expected value.  But I have no idea whether
this would be useful or not.
