Note the word AND. This means 'both', not 'one or the other or both' - that's logically, "OR".To be able to make an
interception, the player must be between the player
who threw the ball and the player who is meant to
receive it, and the plastic ruler must pass over at
least part of the square the intercepting player is
standing in.
