I don't really know, but it does seem unnecessary.

It will certainly be necessary to freeze the grouping selected after students have stared working on the assignment - so that will be why this is done. So, I suppose the question becomes - how can Moodle know when students may have started work on the assignment in their groups? When the assignment activity is first added to the Moodle coures is the earliest possible time that might be. And, the first time a student uploads a response is a latest possible time, but probably too late. What else is there?
