The assignment instruction copies the logic state of the previous instructions executed before. If the previous logic result is 1, the associated bit will be set to 1. If the previous logic result is 0, the associated bit will be set to 0. This way, each time both sensors are at 1, the "Large_Box" will be set 1.
