Core Data Entity Relationship -valueForKeyPath: question

I have a Core Data entity Item with a relationship "transaction." (It's actually a to-many relationship. I'll adjust the key when I migrate my Core Data model.) My question is about KVC. Can anyone help me understand why the following code always returns YES? I know for a fact that some of my Item objects should return NO for this.

-(BOOL)sold{
    return ([self valueForKeyPath:@"transaction.@count"] > 0);
}

Thanks in advance!

Jamie
