The language selection on a post/comment doesn't alter how the content of the post or comment is published. It works in conjunction with the user-level language setting to filter what content other people see. So if you set the language to on your post to Spanish, then the only users who will see it are those who have added either Spanish or Undetermined to the Languages list in their user settings. For everyone who doesn't have one of those two languages enabled in their settings your post/comment will simply not be displayed.
