+          For operations that return a value (typically a value of type
+          `RankedTensorType`), the generated tiled computation has to also
+          recompute a replacement for the results of the original operation.
+          The tiled implementation of the operation returns a tile of the
+          result(s). This methods returns information about what part of the
+          result tensor is computed by the tiled implementation. The manner in
+          which these tiles get put together to get the final result is upto
+          the surrounding loop construct.
+          - `resultNumber` is the result number of the original operation

Oh I see, I had thought it was `index`. `resultNumber` is fine then.
