There is a phenomenon of newlyweds jumping into the shadchanus business. I have actually seen it work a few times. But mostly it fails. There are skills involved, and until one gets to learn the ropes, it is just a friendly gesture that conveys that the newlyweds care for others. As a midoh, it’s a nice thing. But hardly effective.
It does portray that this couple feels happy enough in their newly married status that they would like to share that joy with others. And it is seldom hurtful. On a long shot, not a bad risk.
