Question about chimney cap caulking

Does this “collar” piece need to be caulked on it’s bottom too? It seems like its essentially counter flashing to the chimney cap, so I’m guessing this is installed correctly. Just want to be sure though.

If the chimney cap was built correctly there should be a 1" lip around the hole.

Exactly what I was envisioning. Thanks Randy!
