The CODM doesn't currently support multiple release samples (although we have that logged as an enhancement request for the future), so if you make a CODM organ that uses ranks from a multi-release sample set then only the default releases would be used (the same effect as disabling multiple releases for a rank on the Hauptwerk rank options screen).
However, multiple loops should work normally.
Another question: when the reverb tails are set to a fraction of a second on such a wet set, does that mess up the multiple release situation? Is it even needed on a trimmed-tail output?
If you use release sample truncation, then multiple release samples probably wouldn't make much difference anyway.
