After the break, player one has decided to go for a quick drop into the corner pocket while player two attempts an inane three-ball combo. But is that really the intention here? Player two may be attempting to "tap" the underside of player one's poolstick (completely legal). Player two could have also attempted to shoot player one's "limited use" cueball. What happens at this stage of the game, especially with beginners, is a lot of "tracking" - you decide on a ball before it stops, and you spend precious moments following the ball with your pool stick, waiting for it to halt. To excel here, one must process all possibilities at once and choose one of the earliest ones, not necessarily the most advantageous one. You can see how it pays to be on your toes, mentally and physically. Onward!
