what would you call?

So if the catcher reaches across the plate and obstructs the batter on a squeeze you are going to call CO but if he steps on home plate in the same situation you are going to call a balk?
The criteria for that balk BTW allows the catcher out of the box right after time of pitch. This is not a balk most umpires look for. It could be called with catchers setting up for outside pitches, pitchouts and even catchers that extend one leg out to get lower but the TOP criteria usually is met in those sits.
