I'm pretty sure Siri would react similarly if you asked it about 9/11 or D-Day. It's a helpful personal assistant, not an encyclopedia, and I haven't seen any Apple ads mentioning that you can ask it about specific events in history.
The directions thing is curious, I'll give you that, but then again, it might just be because of the dev beta.
