Just been talking to Simon @ Minispares and this has come directly from AP:

Firstly, they enlarged the bore on one of the ports to stop people getting front/back mixed up. This is the reason why you need conversion pipes when going from the black band master to the yellow band.

The other reason is that there was a problem with air getting into the black band masters. This was down to the plain bore which they changed to a stepped bore in the yellow band master.

And thats it!

I have a split f/r cylinder, ther are two types of brake line sets aswell, one has all metric fittings ( which I ordered)
and the other has unf on the m/cylinder and compensator and metric everywhere else (which my car has)
so Ihad to get the unions changed !! I think Moss list both types of brake pipe sets.

I think the step is just there to increase the the pressure applied to front brakes without increasing the pedal travel more than needed

Just been though this malarkay myself, and after going through several metric fittings whilst making my own brake pipes i can confirm that the larger metric union is 12mm
