WriteMode: overwrite. Autorename strategy?

Question

In the WriteMode (union) the options are add, overwrite or update.

If I set it to overwrite, I think there is no autorename strategy needed.

Still, the documentation says: "The autorename strategy is the same as it is for add".

And the explanation for Aadd is: "The autorename strategy is to append a number to the file name. For example, "document.txt" might become "document (2).txt""

How can that apply to overwrite?

Thanks.

Although less common for the 'overwrite' mode, there are still some conflicts that can occur where the 'autorename' parameter will matter. For example, if you try to upload to a path where a folder (not a file) already exists, that will be considered a conflict and the folder (and its children) will not be overwritten. The 'autorename' parameter will then determine whether or not to commit the file at a different path instead.
