OP's assumption may have some merit if the English speaking reps are also on the Japanese line and anyone calling into the English option would have to wait until the next English rep is available.. at worst they may be placed into the back of the queue to roll through again if an EN rep isn't available, but I can't speak for ANA's internal workings.
