The helmsman must be able to keep his eyes on the person in the water while navigating back for the rescue. Dora and I still practice this regularly. It is a lot of fun and allows us to test our boat handling skills. I am as confident in Dora's boat handling as I am in my own and it makes our experience on the water more enjoyable. This is one of several man overboard recovery techniques.
Some techniques work better in different wind and water conditions than others.
You never know when you will hear a splash. Maybe it will be you.
