Yes exec doesn't spawn a child process but hands over control to another "executable" on the same level, which never returns.

Your trick only works interactively because you need to exec a NEW follow up shell, waiting for human input.

This means this illusion won't work in a non interactive script. All code after the exec will be ignored.
