I'm not sure exactly what a host-to-host cable does do, but it doesn't make either of the masters appear to be a slave. Most likely it includes two slaves that can communicate internally with each other (and each with its respective master, of course). But those slaves won't pass arbitrary messages from one side to the other, only messages that follow the correct protocol -- whatever that is. This means that the slaves can't pretend to be an arbitrary type of USB device, such as a keyboard, because they don't follow the keyboard protocol. They can only pretend to be a host-to-host cable.
