Atom.fn and Atom.fnSync keep their arg state in an internal atom that inherited the registry default idle TTL. When the parent atom has idleTTL(0) we still keep that child atom alive, so remounting the function immediately reuses the previous arguments and re-executes instead of going back to the initial state. Tying the helper atoms (args and concurrent fibers) to idleTTL(0) makes them drop alongside the parent so a fresh mount starts from the initial value and only runs when explicitly triggered.
