Extracting the ISBN from file is just a reading operation. It does not have to guess anything. Either it is set or not.

When you run "Download Metadata", plugins will "try" finding a book that matches your data (Identifier, ISBN, Title, Authors). The quality of this data will determine how good the match is. When you get a wrong match, you can try eliminating your current ISBN, so it will try using Title/Authors.
