**Use of svstep with Vertical-First sub-vectors**
Incrementing and iteration through subvector state ssubstep and dsubstep is
-possible with `sv.svstep/vecN` where N may be 2/3/4. However it is necessary
+possible with `sv.svstep/vecN` where as expected N may be 2/3/4. However it is necessary
to use the exact same Sub-Vector qualifier on any Prefixed
instructions, within any given Vertical-First loop. Also valid
