Nobody called every Slavic population Serbs here. The term Serb indeed had a very broad meaning, but was applied only for Southern Slavs who came here (Serbs, Bulgarians, Macedonians, Montenegrins). Eastern Slavs were allways called Russians (Ukrainians as a etnicity didn't existed till second half of 19th century).

The reason why the language was named sometimes Serbian, I think it's because of strong cultural and religious ties with Balkan Slavs, despite of our location in Eastern Europe near the Eastern Slavs, and far away from the most Southern Slavs.

It is known, what in late 14th century, Serbs were the most influential Slavic people in the Balkans, some Serbian monks came here, so this can be another reason. Contection with the Balkans is seen in local religious architecture too, Old Russian influence is absent in Medieval Moldavian architecture.
