The NCAA is only trying to eliminate extraneous, obvious calls. If the whole ball park can see that the runner is safe, there is no call. The line between call and no-call will be a little different for each umpire and will certainly vary as an umpire gets used to using the no-call. It is just another level on the call chart (ie. overhand sell, vocal hammer, non-vocal hammer, no-call, non-vocal safe, vocal safe, sell safe) that NCAA umpires are expected to put in their bag.
