I think that accurately describes it.

If the resize table is 100% wide and the parent is a percentage, then if you widen the browser window the table will grow but if you narrow the browser window it will not shrink back.
Note, if resize table is 99% instead of 100% it will shrink back down but not smoothly or as expected (jerky resize, and not completed on browser resize end).
