The Story about the Semi-Colon (Continued)

The explanation below was taken from the earlier post.  Can you explain why the commas, semi-colons and full-stops were used in each of the sentences?

1. You, my cousin, in reality helps to make a sentence clear and you also show how two sentences, or complete thoughts, are actually related to each other. 
2. (1) is a complete thought. 
3. (2) is another complete thought but it is related to (1); hence, it shows that while the earlier idea in (1) can stand on its own, the writer is not done with the idea. 
4. He or she wants to continue by adding another, related, idea to it.

1. The commas are used here to elaborate on the `you'.  Who is the `you'?  What is within the commas (`my cousin') reveals who the `you' is, and it also helps to separate it from the main idea so as to demonstrate that this is an extra, or added, information. The same goes for the `or complete thoughts'.  The commas allows one to relate it to what comes before, namely the `sentences', thus, demonstrating that `complete thoughts' are the same as `sentences' and are included to stress the fact that they mean the same.
2. There is only one idea here and the writer wants to express just that one idea, hence, the full-stop is used at the end.
3. The idea that comes after the semi-colon is related to the idea that comes before.  The second part, after the semi-colon, is there for further explain what is meant by the first idea contained in the complete thought that comes before the semi-colon.
4. Again, the word `related' found within the commas is an added detail, to further describe the `another'.
