Chuck,
Let's say you are rolling a ball back and forth on a table and it is my job to tell you when the ball rolls off the table and hits the floor.
If the ball rolls off the table and hits the floor I say "the ball fell off the table and hit the floor." Duh, that is what I'm there for.
So, the ball rolls off the table and right before it hits the floor you catch it and begin rolling it on the table again. If I say the same thing it would be interrupting you because although the ball rolled off the table you were able to recover and continue rolling the ball on the table.
Maybe a bad example, maybe not.
