index save set level and flag

Hello,

I have a tape storing some save sets which clone retention time has expired but it is still in "recoverable" state. so the tape is still not recyclable and re-usable yet. These save sets are index save sets:

Can someone clarify to me when these index save sets will become recyclable. It seems it depends on the level because when I looked for this specific save sets I found that  level "1" ones are expired:

mminfo -avot -q name=index:issbra02 -r "volume(20), client(30), name(8), ssretent, clretent, level, ssid, sumflags"

Will these full index save sets ever become recyclable also? if so when?

Thank you.
