I live in Ireland but currently in Hong Kong. I bought Farcry 3 and Dishonored today on Steam and I'm wondering if it will work when I'm back in Ireland?

When I was purchasing both games I just changed the billing address to the one I'm currently at in Hong Kong and it worked, the currency displayed are in dollars and not euros and there was no warning messages. I'm asking this question as I'm afraid those games could be region locked when I get back to Ireland and I end up wasting my money.
