Comment (by dougal):

 This is expected behavior, and working as designed.

 The `wp_trim_excerpt` filter is used when there is no manually set
 excerpt, and WordPress is automagically creating an excerpt based on the
 full post content.

 By passing a long string through the `get_the_excerpt` and `get_excerpt`
 filters, you are simulating the case where you have entered the same long
 text into the `Excerpt` field in the `Edit Post` screen. When a custom
 excerpt is present in the `$post`, no trimming is done (though other
 content filters are applied).
