You seem to have a different opinion on what "sequentially" means. The meaning I am aware of for "sequentially" means "one after another", which means that no two commands may be running at the same time.
You seem to want to run two commands at the same time - first the command that sets up the environment and starts a new shell, and in that shell run another command.
The solution of piping in the commands into that shell or the solution of retrieving the environment settings from that shell are both approaches that can help here.
