The description of forcing the zero's above is one that indicates that the spreadsheet removes the zero's on "import" and that the command would force zero's to be placed not requiring you to find and type them.
If the zero's are in the csv file, EP4 is not the case of them disappearing later, but instead the spreadsheet/import process to the spreadsheet. (In some spreadsheet apps, it is possible to identify a column to be imported as a text field that would keep the zero's in place.)
