Strange thing about server selection

So I wanted to find people today to do Leo daily with, most were US-server though and we decided to all switch to that server. So I logged out, switched to US but still got queued into the EU queue automatically.

I don't know whether it's intended or not, but when I chose to join the US server I should be queue US as well or am I wrong?

Ok little update on that. Someone else from US server tried to get me into the US queue so we dueled and suddenly I was in US queue after queuing up for PvP again.
After I logged out though and reselecting EU server I'm still getting queued for US now. Any ideas?

I find the first duel after switching always happens in the old server, perhaps its tied to how our hideouts are still in the old server even after switching due to persisting instances?

but then there is no way getting around it with pvp-only chars
