Separate model group created for follow-on-orders.

Content (please ensure you mask any confidential information):

We are performing follow-on-order to a model present in the Line-Item Grid. The action is creating a new model group during this process. Action code is updated for the new the model group. But we wish to see the changes in the already present model group itself. Why is an entirely new model group created during the follow-on-order scenario?
