This isn't the whole picture, if I follow your layout.
Not quite sure what is going on at the gutter, but from there it looks like the four coax run down to the ground blocks.
Now what happens from here?
They should be running to the SWiM-16, and then this is where things get important.
Take a few photos of the SWiM-16, and the splitters coming off the two outputs.
Here are some more pictures.
1. Another picture of gutter area
2. 2 cables going down wall.
3. Connection on house
4. 4 wires going into house
5. 4 wires from house are connected to the 4 slots on top of swim 16
6. The 3 cables on left side of swim 16 (see previous pictures) are connected into the 2 green splitters and 1 power adapter.
The splitters have 3 connections to each. Still not sure exactly why there are 3 connections to each as I only have 5 boxes.
Hope this helps, if you need something else, let me know.
