Actually its designed to make sure that the data model underlying the table does not change until newly posted values are compared against the old data and change events are fired.
Otherwise it is possible that the data in the db changes while user is looking at data. When they post, there are erroneous changes unless you temporarily preserve the data model. The data model is then updated in the normal manner during renders response. At least this is how I understand it. I haven't used it yet though.
