Conditions can do a lot more than substitute a value. Think of it like an exception in reverse, you can resume with different "types" that cause it to take a different path. And they might pass new data in. Say you have a function that is basically a loop processing a list of files, it throws some kind of "file not found" error. You could sort the file out and do a resume "try again", select a different file and do resume "diff file (filename)" or do resume "skip".
