I believe that they are referring to the ease with which passwords used to
protect the Workbook or Worksheet(s) can be broken. While a worksheet is
still protected, with or without a password, locked cells will remain locked.

Microsoft acknowledges that the 'Protection' is more to preserve formulas
and content from accidental change than it is to actually provide security to
the workbook or worksheet.
