If you really accept doing thing "the wrong way" with IPv6 then feel free
to have problems. Wrong Way is not using /64 on a LAN. There is no real
shortage of adresses even if each customer/VM get a /64 so please ask
the provider todo the right thing:)

About the specific problem, I just tried it here on my LAN, I could route
and use any IP addy on my Linux box and outgoing ssh session would
use the newest IP address no mather what netblock I picked it from.
Sound a bit strange the issue you're having :/
