Whatever you think of Brexit, is a pretty sound procedure. Those laws are already valid in the UK, so by bringing them in you ensure there are no disruptions, while giving yourself time to amend them / replace them with new ones. It also signals that the UK is doing an orderly Brexit and that it's "open for business". I suspect laws dealing with human rights, which May was quite strongly against, will be the first to be repealed the moment EU membership is officially up.
