So it seems - they appear to have reversed the order, making it inconsistent with the UNO.
What a mix-up. Also mixed-up is the "Products" page when I attempted to find the reference for the "Mini" which is missing. 
(Starts searching to actually find a Nano to examine. Gives up after finding some "Nano 3" variant boards. Too late at night ...) I give up. 
These days, I'm not sure the "Arduino team" could reliably organise a chook raffle!
