What is Excel Document Recovery offering ?

The Excel pane labelled "Document Recovery" offers the following help...

When an Office app closes unexpectedly before you save your most recent changes, the next time you open the Office app, Document Recovery automatically opens to help you get your file back. Document Recovery lists any files you had open that were recovered from the most recent time you saved them, the most recent time they were AutoSaved (if your file is on OneDrive or SharePoint and you are a Microsoft 365 subscriber), or the most recent time they were Auto Recovered.

A file "recovered from the most recent time you saved them" means they are offering me something I saved intentionally or that I saved intentionally via AutoSave because I enabled AutoSave and I have awareness of the passage of time.

Why are the offering to recover something that I saved? If I saved it then it would seem that I don't need any recovery intervention. Wouldn't it make more sense to recover something that I did not save ?

What is the practical advice for dealing with this? How should this help be written to be easier to understand?

I probably shutdown Windows before saving and closing a file.

Edit:

Not knowing what to do with that inexplicable help information. I closed the file without making a decision. I reopened the file and saw the same Recovery pane. I closed the file again without making a decision. I reopened the file and there is no longer a Recovery pane. This is strange.

Refreshing the "Windows Explorer" view, I can see there are no temp files with weird symbols in their names. I presume that recovery information is usually stored in temp files with weird symbols in their names.

If the absence of the Recovery pane and absence of weird file names means that there is no longer any possibility of performing a recovery then my problem is moot. This is very annoying.
