It's not moot. Even though it is O0, some of those may be trying to upgrade to J, which is J6. So if one of the PY passengers gets moved up, a seat opens up for someone trying to upgrade from Y. Also, there could be no-shows in PY, perhaps due to mis-connects or just changes in plans. So don't give up hope.
