Haha - I have no idea!  Sounds good to me though.  I would say you were right.

It just shows that I need to understand more about this stuff.  I have only ever heard using a diode like this as "polarity protection", which is I guess what single diode rectification is.  But it does more than just protect the circuit.  If you only ever use good quality power supplies - like I do for myself - then you may never notice it missing.  But if you sell or lend pedals it's probably good to know that sometimes a diode can be helpful.  Just as a 1ohm resistor can cut down noise in the right place.
