It shows how many people cannot think for themselves and need government to think for them.
So in this case, Polish-Lithuanian relations on government level are not so good, so that automatically means it should be same thing among regular people? Yet in 2008, results differed by around 40%!!! It is really stupid and quite sad.

Poles and Lithuanians lived alongside each for centuries and some still do (especially in Polish and Lithuanian diasporas).
Pity that few idiots in government can spoil whole relations between peoples.
