Medicine in UCAS Extra

Do you think the university would check? If a student said they clicked the wrong box and were actually only resident in the UK for educational purposes they might get away with it.

I know on newmediamedicine there was a discussion between two US students where one said he'd used a UK address to apply and had a UK passport though had never actually lived in the UK - he said he was assessed as a home student. May be BS but hard to know.
