Well seeing as your function is LoadConfig_data, where is it going to get the 'data' from? So by having %s, it will load LoadConfig_?, where ? can be anything and it will still load all associated files. It's not so much something to do with formatting strings, but telling the script to load anything that begins with 'LoadConfig'.
