Paragraph for optional relationship without dependent loaded makes no sense

Hi

According to the last table on the page, `ClientSetNull` throws an exception, but according to the text right below, `ClientSetNull` is the default. How does it make sense to have a default value that results in exceptions being thrown? I don't know if the table or the text is wrong, but surely the default results in the FK to be set to null somehow 💯

Also the notes disagree with itself:
> Notes:
> - Severing a relationship is not valid here since the dependents/children are not loaded.
> - The default for optional relationships like this is ClientSetNull.
> - Dependents/children must be loaded to avoid a database exception unless the database has been configured to cascade either deletes or nulls.

Point 1 says dependents must be loaded while point 3 says configuring cascading is okay even when dependents is not loaded?
