When you update an environment in Murano it will update underlying stack. You should not see a new stack for the same environment. If you have a PostgresDB deployed and then add a Tomcat application you will see that stack was updated with new resources. There is no dependency between Tomcat and PostgresDB so deployment will just update Heat stack with independent resources (new Nova:Server will be added). Murano will never add a new stack for existing environment when you update it. There is no such logic in the code for sure, a single Heat stack nailed down to environment and each deployment will do stack update calls.
