Without these dots, the glass could become loose and eventually fall out of the frame. These frits are also there for aesthetic purposes.

As they write in the article:

the windshield glass in modern cars is bonded to its frame using a strong and long-lasting urethane adhesive.

"This makes the windshield a structural component of the vehicle's body," explained Reina. "The frit is black painted enamel that's baked onto the surface of the glass, and it provides a secure point of contact between the glass, urethane adhesive, and windshield frame."

I also quoted the article. I understand that part and the black stripe, but I don’t understand how the dots help in this.

The dots themselves don't do anything, but the black border does. But if you see the dots coming off the glass, it's a sign that the frit around the edge may also have started detaching from the glass.
