Why? Radio with only one item is not a special case and will get handled in exactly the same way as multiple-option one. As far as I can see this function always returns true, if radio option was selected and false otherwise. It's just not a very direct way to do this. For example condition in return says basically, if retorno is false, return false and true when it's true. So why not just return retorno?
