It has to be a punishment that was in effect at the time the crime was committed. Under your example, the crime is committed after the law imposing the requirement was passed (albeit only a day later), and if under that Act that punishment would apply to that crime then I agree with you that it would not violate the Indiana ex post facto law. But we have to start with the date the crime was committed to know what law applies, and we don't know what date that was. We know only that the conviction was entered in 2000. The act itself could have been committed before 1998 for all we know.
