You're right, the emergency and delivery access bits are swapped.
Here's what I said in commit 965:

    Assign new values for bits that block emergency and delivery 
    access. 

    I am pretty sure that these two access bits go into the top two bits
    of the net pointer - I am not so sure that I have them the right way
    around - we need to check with an example map that has one of them
    set and the other clear to confirm the ordering.

Guess I forgot to check if they were the right way around!

Cheers,

Mark
