Solution

This is the expected behavior.
A User can generate the layout / document using WebADI.xls only once for security reasons, although the Book1.xls can be used for multiple uploads.

There are two ways to create a Document/ Excel Spreadsheet. When first Creating the Document there is the option to either:
Open Save Cancel.

If you Open the Document and then save if from Excel, it is generated as a Book1.xls.
If you Save the Document, then it is saved as a WebADI.xls.

The user can use the WebADI.xls only once and then they get the "This  document has already created" message. 
The user can upload Book1.xls multiple times.
