As I've said I suspect Card knew what it meant on some level. However, I'll concede that he may just have been using it in the Harry Potter way you mention, like "Damn", "Bloomin'" or "Bloody".

But it's interesting when companies, producers, writers, directors etc are unaware of a word's other meanings...
