The idea of this move helping with decentralization is that it provides another avenue for Steemians to access their Steem Power and power down. There are only a couple applications outside of Steemit.com where one can do that. I believe busy.org can do it but steempeak cannot. Steemworld is another way. Those are the only ones off the top of my head. And now we can add Actifit to the list.
