Can anyone please explain to me this Canadian/EU Exception?

WHEN TRAVEL ORIGINATES IN A COUNTRY FOR WHICH
THE SPECIFIC LOCAL CURRENCY FARES IS PUBLISED AND
THE TICKET IS SOLD IN ANOTHER COUNTRY THE FARE
WILL BE THAT PUBLISHED FOR THE COUNTRY OF ORIGIN
CONVERTED TO THE CURRENCY OF THE COUNTRY OF SALE
AT THE BANK SELLING RATE.
THE RESULTANT FARE MUST NOT BE LOWER THAN FROM
THE COUNTRY OF SALE. EXCEPTION -
NOT APPLICABLE FOR SALE MADE AND/OR ‡
TRAVEL ORIGINATING IN CANADA OR THE EUROPEAN
UNION.

Does this mean that when buying in EU, I pay always the price of departing country?

a) Buy EU, start S.Africa = old rules EU price, new rules S.Africa price
b) Buy EU, start EU = no change
c) Buy S. Africa, start S. Africa = no change
d) Buy S. Africa, start EU = no change (you pay EU price)

Anyway, this is great news I guess Mindpearl will be a bit less busy now.
