Deploying models with the same name

Hi,

In AX 7, if I create new model using the same name from different environments, when I deploy to the same environment using deployable package, that will be the same model as well?

e.g. Devbox A, I create MA model

      Devbox B, I create MA model

In the UAT environment, if I deploy the package from DevBox A and B, they will be end up with the same MA model? And if there is anyway that when we deploy the package, can I change the target model at that time?

Thanks,
