You are misunderstanding the EFC.
The EFC presents all persons related to a selected person, whether by blood or marriage. (if the "include everybody in this file" option is unchecked.)
If a person is connected by marriage - AND they have their blood relatives entered (parents, children by other spouses, siblings, etc), that family will be presented as an island - separate from the family where the spouse was shown as a spouse.
Each "island" connects to the island from which it "sprang" by reference to the person who married into the other family via a number in the upper right of their box. This is how the islands are connected.
This is very visible when viewing the report on screen and one uses the "person locator" gadget in the lower right of the screen. If a person shows up in more than one island, it will show the multiple instances and you can "jump" from one to another.
If the EFC report is printed on paper and you have few dozen to a few hundred to a few thousand people, with extended family entered, it will be very difficult to find these connections. This is what the original poster was originally complaining about - to which my reply was: what other option is there besides the numbering sequence of the person in the islands in which they occur? You can use colors or lines, but both are unwieldy and not practical once you get a file with a few thousand people in it.

As for your example, I am not familiar enough with the file you are drawing your data from, but I suppose you have the "Include all individuals in this file" option checked.
Another possibility is that you have the number of generations set to a number that is too restrictive. I have mine set to 99 generations so that it catches everybody related to one another being in their appropriate island.
If you go back to my example, you will see how the EFC works:
Two separate families.
Connected by one person in both: who is a child in one island and in the other island is a spouse.
That one person appears TWICE in the report (in two islands) and has the number (1) in the upper right of their box - which connects the two islands.
