Maybe I am wrong, but I am just uncomfortable with anything involving putting screws back in the holes. It just seems like a bunch of spiral pathways for water to get in!
It is not. Since there is Dicor in the hole and a bit on top, the threads of the screw become wrapped in caulk as it is screwed in. I have removed screws that I had installed years earlier and they still looked like the day I screwed them in. There is no way for water to get past the head of the screw with the caulk under the head and over the top and the threads themselves are also wrapped in caulk. Heck, look at all the roof vents and similar things on your roof. They are all screwed down and don't leak.
