I'm not the one who reported it, but I do seem to remember a similar situation with another bug report a while back. Release does not involve any targeting, the players choose and sacrifice their permanents as part of the spell's resolution, and since a card always resolves in the order it's written, the Catch half goes first (Rule 702.101d, left halves go first), meaning that by the time the Release half comes, the targeted creature from the first half has already switched sides as part of the resolution currently going on.
The
Gatherer page for
Catch//Release actually says this, now that I checked:

Catch/Release as a fused split spell, you can sacrifice the permanent you just gained control of.
