why does water seem to not stick in the path of the windshield wipers?

I was washing my car and noticed that every time I spray water on the windshield, the path of where the windshield wipers wipe, is like kind of dry/different than the edge parts of it.

Why does that happen?

Some wiper blades are coated with solutions similar to RainX which allow the water to run off of the glass instead of form into drops.
