It seems you are using same database used by
http://directory.io/ as we can see all of the address on first pages are same in both.
- Create Addresses Based on words (Brain-Wallets)
There is no need to create a bitcoin address on your site which on later may get exposed in the list. I don't know how your site can be useful..
The UI is much more simple and you get direct access to the address funds. (last column of the table)
There is no database, all the data is calculated "on-the-fly" - this is not a copy of directory, but all private keys listed and sorted
Also when you generate a new address (based on a word - brainwallet) you get the address available funds. That may be useful to create an address not for your usage but for quick balance check only
