The th element is an actual cell that will contain header content to be displayed. It would be inside a row.
As to the scope attribute, it's true that heading cells in a thead row would generally relate to a column, but their might be some value (perhaps for styling or scripting) in explicitly defining their scope with the attribute.
The potential uses of the thead element and the scope attribute are not quite the same. The thead indicates entire rows containing heading header information. This could be used to include the header rows on each page of a printed, multi-page table, or to present a long table with a scrolling body and static header rows.
The scope attribute defines which cells a specific th header cell relates to. The th element is not only used for column headers, nor is it restricted to rows in a thead. The scope attribute might be used to give special styling to certain header cells based on their function.

My question was why would you use both simultaneously when they achieve same exact thing.
