It's bullshit (I'm on a Dutch Works Council). The Works Council decides over matters within that country. So anyone in that country is (more or less) represented. Could be a bit more difficult if there's multiple legal entities, especially if some of those are too small. A German Works Council can hold all of their meetings in German. A Dutch Works Council can hold it in Dutch, though German one can really force more things to be in Dutch. The Dutch Works Council has non-Dutch members, the meetings are in English, etc. If a change is also about something outside of NL we do not deal with it. Similarly, if there's some change in some other country we might not even hear about it (which is totally fine!). If the weird statement is a fake fear about employees in another country: setup a similar Works Council in that country. An employer can easily give additional rights, meaning: setup a Works Council-like thing in a country where you aren't required to have one.
