Subject: Crafty positional learning questions

Crafty has antisymmetric evaluation so how can it learn from white about black?

I learned from the winboard forum that Crafty can learn from a game that it lost
with white about moves to play in black.

When does it learn to do it?(only if the relevant position is one ply after it's
move or also later) and how it goes with Crafty antisimmetric evaluation.

Suppose that Crafty is white and the opponent chose to close the position with
black and won the game and Crafty had negative score against itself because it
dislike closed positions.

Does it mean that in future game when Crafty is black it is going to learn that
the line of the opponent was good based on it's score and it is going to close
the position.
