I believe that the arrangement of the serratus muscles will not allow this movement to be of any benefit to this particular muscle group.
It can help in the development of chest and back muscle as Rocky said. Hand placement and form is key. The style of leaning over a bench is not as effective as using a cable while standing IMO.
As for it increasing your overall girth - bull****...
