No, it shows they can have their firmware upgraded in what is known as "DFU mode" which is a pre-boot state. That's to allow recovery of a bad flash that gets interrupted, or if a new iOS version caused a phone to not be able to fully boot up.

They may secure that - I wrote a post suggesting a way to use key pairs to authenticate against an iTunes install with the phone unlocked, which the phone would have to be connected to in order to update the OS in DFU mode so it couldn't be done with just any old PC/Mac.
