That's... an interesting way of turning a motor on and off with a button. A slightly cleaner and more expandable way is to use the Select function block (in the Programming>Comparison palette), or a set of Case Structures. The Select function block has one boolean input (green wire) and two other inputs that can be of many different types. It selects which of these two other inputs to pass to the output based on whether the boolean is true or false. I've put together the motor control you were looking for in the picture below using some select blocks. This particular wiring forces the forward button to override the reverse button. So if you have both buttons pressed, the motor will move forwards.
