I think you guys have all the parts, but it can be stated more simply that what you have.
1) all the sediments at one time were silt-sized, and these formed the loess deposits.
2) the river runs through and cuts loess deposits into loess cliffs
3) over time the river meanders making one side of the river flatter (point bar) and the other steeper (cut bank)
4) what we see today is the result of a continuous eastward migration of a meander cutting into the land leaving flat land on the west side. It is now a straight portion of the river.

What kind of scale are we talking about? Like the river moved 50 feet? Or 5 miles?

North of Vicksburg the delta is on both sides? Haven't been on the Arkansas side of the river there.
