So, if this continues to be part of the algorithm, and if you are putting your stuff into Yahoo Shopping for the Yahoo Store as well as for the other site, that's a possible reason.
The other one I can think of is if you have urls of the store.yahoo.com/yourstore format floating around in search engines, you will lose them if you close it (or if you "upgrade" to Merchant Solutions, but that's another issue).
