you are willingly ignoring the fact that he has two passports unlike something.
i can give you the example of russ, an ex guild player. he is currently eligible to play in both the emea league and the pacific league without being counted as an import in either of them. coz he's both british and sri lankan (you can check his twitter LFT posts). thats the same for derke, however he's russian and finnish.
and something is russian. most of the russian population lives close to europe and that is why entire russian country was made a part of emea rather than pacific. the reason smth is emea is not arbitary, its just to simplify things. it would be much more complicated if people from one country were by default eligible to play in both the leagues.
it sucks for something, but thats how it is. my point stands.
