This is powerful feature, but the demo example doesn't really give justice to it. There needs to be a good reason to use it. Resorting from name to size of the file it not it.
For instance:
- Filtering down to a small subset from a large set of visible items. It makes sense to use this effect in case the selected item's representation is zoomed or displays additional detail. The animation indicates that there's a relation between the selection and the larger set. It also gives a clue original distribution of the selected items within the larger set.
Example: Show all facebook connections groupped by country. Then select those that have a particular interest as a list. The animation would give you a clue about geo-distribution of people having the same interest. This clue is an additional information you could not see by simply showing the selection.
- Reordering (eg. promoting) a small set of items in a large set. The animation shows you how far the item travels when it is promoted.
Example: Display the list of tennis players according to their rank at after a given competition. When the user selects the different competition, the list is reordered. The payers who make big jumps attract more attention.
