I doubt enough water gets that high up through those narrow necks to clean anything.
I always scrub them well with a bottle brush, washing soda, rinse a few times and then sanitize with Starsan. The dishwasher can be used to "sanitize" clean bottles but I would not rely on it for cleaning the inside.
