You are wrong. All .org domains will be priced the same as will .info domains. They can't decide a particular .org domain is worth more than another (that has already been registered and is being used). They can charge what they want but they can't differentiate between domains. And the quote you gave essentially says that.

This is different than a completely new tld whereby they might decide that a name is premium. The point is no legacy domain will be priced as premium. I guess in theory if it expires they might be able to do that but the 'can charge what they want' will not impact existing domain registrations. And in the case of a valuable domain if that were released it would be grabbed at auction and not available for the simple registration fee.
