 Unlike the parallel case, A is not itself partitioned, so is copied
 over as much as is possible.  In some cases such as `1x 4-bit, 1x 12-bit`
-(partition mask = `0b100`, above) the 8-bit scalar source will need sign or zero extending.
+(partition mask = `0b100`, above) when copying the 8-bit scalar source
+into the highest part of B (o3) it is truncated to 4 bis (because
