To be able to post up or to kick it back out to the SG.
The SG starts with the ball at the left wing of the arc. The PF moves to catch the ball near the low left post, who then posts up on his man. (This will draw the SG's check.) Now he can take the shot or kick it back out to the SG who has moved either to the corner or near the top of the key.
If the SG has not moved when he passed the ball to PF then this makes him easy to find again. The SG should move so that his check takes longer to find him.
This drill/play can be used for any player and on either side of the court.
