No, the cores are getting the same indexes numbers as before. While
scanning core_num is increased for every core found also for cores we
are not searching for or we already found. Then core_num will be
assigned to core->core_index. bus->nr_cores is no used any more so it
could be removed or is it needed for something else?

As you can see here [0] it finds core 0 and 3 at first and then the others.
