Like dleslie said, speculating obviously. However since this is about compliance with EU law, actually location has nothing to do with it. It's about being a EU citizen.
If Facebook refuses to do the deleting thing for an (actual) EU citizen because they claim their location tracking shows they aren't located within the EU, they are going to have a problem.
If, however, the EU citizen selects in their profile that they live in the US, and then FB refuses to delete their data, the courts are probably going to look favourably on them, cause the user explicitly said so.
Since FB most definitely is absolutely, unforgivably, NOT allowed to request or handle the nationality data in EU passports, for purposes of being a EU citizen, they're pretty much going to have to rely that you're whatever nationality you say that you are.
