Early Decision Policy

Hello everyone,
I came across this while applying,: As an Early Decision applicant who is submitting a complete application, I agree, if admitted, to be bound by this decision. If admitted, I acknowledge that I must immediately withdraw applications from all other law schools.
So this means I can't go anywhere else but this university in case I am accepted. Like what I am not able to afford their prices? Can't I go anywhere else? And is this the same with all early decision applications?
