In post-Soviet countries we have 2 types of passports: one internal which is used as id card and second is for traveling. So for most people there, passport is like a synonym for citizenship.
Interesting, I'm from Hungary (pretty sure that counts as post-Soviet), and I've never heard of such a thing.
I'm also pretty sure that the internal passports are 100% irrelevant to this site and one would get confused by this only if they really, really wanted to.
