  * \brief          Baseline multiplication: X = A * b
- *                 Note: b is an unsigned integer type, thus
- *                 Negative values of b are ignored.
+ *                 Note: despite the functon signature, b is treated as a
+ *                 t_uint.  Negative values of b are treated as large positive
+ *                 values.

  * \param X        Destination MPI
