in the technical sense, no it's not.
if a prison's wall collapses one night, and someone who is supposed to be there for 3 years finds his wall gone with one year left, does that mean his time as a convict/prisoner are over? no! he gets hunted down and dragged back, often for a much longer time. now, since in hall's case, he's outside and we don't want him in, i'd say he should get his ban increased if he comes back before his date
