Catch question- Bizzaro world play

[eagle_12]

I understand that the runners don't need to wait for a "catch" only first touching. As it says in the play, the defense is trying to trick the offensive runner(s) hoping they don't know the rules thinking they have to wait for a catch.

My question is simply catch or no catch. Does he show complete control and voluntary release even though there is no firm and secure possesion.
