I have see that many times. For me it just shows how bad is the 3D engine. Every situation that you see is already pre-defined and 3D engine just tries to show it, sometimes it shows total non-sense. There are some pre-defined animations that will always end in a goal, such as: before mentioned pin-pong. Another example is when goalkeeper saves shot but the ball bounce back to same player - then you know that his second shot is 100% goal. There are other cases where you can tell 100% goal is coming.

Poor simulation...
