Is "distribution" that important when submit app to AppStore in Xcode 4?

What happen if you don't create "Distribution" inside of the Code Signing window?

Because I just submit my app to appstore, and it doesn't seem to have any problem with it though.

I use Distribution is for Ad Hoc and Release is for for App Store. It's just a name, how it works depends on what code signing you choose.

If you go to iOS Provisioning Portal, select Building your Application with Xcode for Distribution and you can see they duplicate the distribution option from the release option.
