No, not at all. I have found three of my ancestors in these records who were from what is now Slovakia but was part Hungary before WW1. Two were from Gomor County and one from Zemplen county. Two of these men had been shot and were in a hospital. One was shot in the battles against the Russians in Galicia and was in a hospital in Reichenberg, Bohemia. The other one was in a hospital in Kreinsier, Moravia. So that established their connections to the Czech regions. The third soldier was from Zemplen and was killed in Serbia. But he was still listed in the casualty reports without any connection to Czech regions that I can see. It is easy to do a search of all the records by surname. If you have a common surname, then I used "surname + birth town" which worked to limit the hits.
