Of course it will be used as 1918 space. That's not the point of the text.

The text is saying, "You could read 1918 to say that we somehow promised 
that you would never be connected to a network run by someone other than 
yourself and see 1918 addresses on it. That's not an entirely 
intelligent reading, but we see how you can read it that way. So, if you 
built yourself a device where it isn't able to deal with 1918 addresses 
on its 'outside' interface that you were using on the 'inside' 
interfaces, we could see how that might happen. It was not at all smart 
of you to build your device that way, but you probably were technically 
within spec. Now we're adding some address space to the pool. It's not 
global and it's not routable, just the same as 1918 space. But we're 
letting you know right now: You *will* see these addresses on networks 
that you don't run. If you want to use this space the way that you used 
1918 space, peachy, but understand that if you're unable to deal with 
these addresses duplicating ones you're using, your device is toast. 
Deal with it."

Any thought that the text is saying something more than this is nonsense.
