First Year Away

Hi, on the common app it says that if you can’t be admitted directly into your desired school (in my case CAS because I am a psychology major) that you can start in any of the 5 locations and study abroad the first year. Is this just to complete you gen ads the first year then for the next 3 go to your choice campus (mine is NY) Idk I’m so confused if i should even put it because I don’t want to study abroad for more than one year. Anybody done this before???
