You're absolutely right...it doesn't apply if I start again from clean. 
I have no idea why - it must have been something I did when applying the patch in the first place but I'm at a loss as to what. Urgh :(

I'm regenerating the patch and will resend as a v2. Just going to run some tests as a sanity check first.
