Why user from one instance of VBS is available in another instance VBS as a team member or owner
In Organization we are working on more than one Fusion instances and VBS instances. In one VBS instance we can able to see users from other instances when we try to add team member in VBS project, and system is even allowed us to add those different instance user as well, why it is allowed and what intention is behind this?
Also when we added other instance user as a team owner he can able to see this project in that VBS instance where that user is belong and asked to create Environment for that instance from the project is belong. If we create environment then does that project get created in user's instance with new GIT repository and does it created new package and deployment build jobs ?
