You are right that is what the pre-game boards show. Just like anything not produced by the organization that are ultimately responsible for the mechanics, you will not have accurate information all the time.

Peace

The women's mechanic fosters more communication between partners because you need to see that the lead has taken the responsibility of the ball rather than just blindly passing it off -
It also allows for the lead to make the choice to stay with a competitive match up that could be a problem (and see the whole play in the post) rather than let it go and miss something in the transition or have the T just see the retaliation rather than the intiation of hostilities. Also since you are supposed to be as wide as the ball (almost out to the arc) - when we make that transition it is more seamless.
This also works better because in the women's game IMO there is less actual banging in the post than in the men's game, so we can make that transition to the ball in most cases and we do not lose anything in the post area.
As far as the side line, you are not supposed to go wider than about 3-feet inside the arc, so you really can not effectively work that side line area it needs to stay with the T, but you can effectively pick up that corner trap and the 3 point shot from that position, rather than being 15 feet from the play.
