Question - Grandmaster Ice Clone Mechanics

[MushinZero]

In an effort to fully understand my main character, could someone explain exactly how the ice clone works or, more specifically, why sometimes it does not work?

It appears that in certain combos, or at certain spacings, or timings, or when the opponent is in the air, the clone will not come out. Do we know exactly what these situations are or why?

Clone lasts for 4s, on cool down for 5s. Ice statue may be a little different, I'm not sure. From what I can tell, in neutral the clone won't come out if opponents standing animation is already within clone hit box (same when opponent is knocked down or in the air, something to do with their axis on screen). Mid combo, clone will only hit/ freeze if the opponent is about waist height or lower (differs between character models, higher for large, middle for male, low for female). Clone now disappears if clone is hit by projectile, if SZ is hit or forced to block an attack.
