I think I was wrong. I just re-read the help

XLS
Creates a Microsoft Excel version 2.0 worksheet file. Each field from the currently selected table becomes a column in the spreadsheet, and each record becomes a row. If you do not include a file extension, an .xls extension is assigned to the new worksheet.

Note
Though you can export a maximum of 65,535 rows, which includes one row reserved for the field header, versions of Excel earlier than 8.0 (Excel 97) display only the first 16,384 rows and cannot import files containing more than 32,767 rows.


XL5
Creates a Microsoft Excel version 5.0 workbook file. Each field from the currently selected table becomes a column in the spreadsheet, and each record becomes a row. If you do not include a file extension, an .xls extension is assigned to the new workbook.

Note
Though you can export a maximum of 65,535 rows, which includes one row reserved for the field header, versions of Excel earlier than 8.0 (Excel 97) display only the first 16,384 rows and cannot import files containing more than 32,767 rows.

So, it depends on your Excel version.
