No, this is not roughing the passer, by description, but is a personal foul for under 9-1-2, striking. The penalty enforcement is essentially the same, since this penalty can be added to the end of the play (if a legal forward pass that crosses the NZ), enforced at the end of the run (if beyond the NZ), or enforced at the previous spot.
By your description, the call was righteous, but the announcement may have been inaccurate. Tomato/Tomahto. But yes, we should make correct announcements.
