I think the idea is to not think so much about organising them. If you consider that the target audience are the users who just have page after page of random apps and never got round to sorting them out, I doubt they are going to bother renaming or rearranging the folders either.
So I imagine Apple's intent is more along the lines of - just trust us to organise the apps in a manner that will be better than whatever system you have been using all along, which I believe is going to be true for the majority of users.
