No, that wasn't my point.

What I meant was that not all softball organizations instruct their umpires to call an illegal pitch as soon as it happens. ASA does, of course.

There do exist sanctioning bodies that instruct their umpires to call the illegal pitch when the ball reaches/crosses the plate, regardless of when the infraction actually occured.

Since the OP specified no organization or version of softball, calling an illegal pitch as soon as it happens might not necessarily be Umpiring 101 in all cases.
