Keep in mind that a table occurrence does not store any of the records. It is the means by which that data is accessed from the table on which it is based--whether via a layout, a relationship, ExecuteSQL or imports and exports.
A table is a definition in a file/database.
A table occurrence (aka table alias) is a graphical representation of a defined table from: the current file, another file, an external file (ESS for example). TO is what you see on the RG (relationship graph), is what is tied to the layout, is what is seen in drop down table selections, is what is used in calculations, is what is called in ExecuteSQL() and other functions, etc.
That the defined table may have the same name/label is purely a choice.

If I have understood correctly and am sure I will be corrected if I am wrong, but a key differential between the table and the table occurrence (TO) is the mechanism by which latter allows the linking together of related tables (specifically their occurrences).
If I have understood correctly ...
Well no. Everything on the graph (except text notes) is a TO.
I was not stating what a table was nor what a table occurrence was - merely a key difference between the two. Have I not understood correctly?
Yes. You have not understood correctly.
My stated differences between the table and the table occurrences do seem real to me; unless proven otherwise.
Yes! That does help you understand the differences. The TO is used for 'context' in many places and your understanding in your OP is correct (linking/not linking & groups linked together).
1. You've defined (table)
2. You've placed it on the graph (TO)
From there on the context is what is on the graph and what is linked (or not).

There are two common sources of confusion in FileMaker for new developers:
a) defining a new table automatically produces a table, table occurrence, and layout with exactly the same name. The names are the same, but these are three different items.
b) throughout the App, the developer interface refers to table occurrences as tables.
