I think you have read JFs post wrong, in his example he has LEFT rudder and right aileron, ie. you would have the right wing down in a sideslip and you would roll LEFT ie towards the UPPER wing.
(correct me if i am wrong please John) as you say yourself.
Possibly oversimplifying it - rudder Left- spin left, rudder right - spin right. Not ALWAYS true, but for our purposes I would suggest true enough. (And ALWAYS CHECK the spin direction if unsure for recovery - assuming you have the height
)
