IMHO, the 'quirk' is that the booking engine quotes a price in USD
The ex-Sudan fare is quoted in SGD, not USD. Imagine if you were in Khartoum and used the booking engine to buy a ticket - why should you have to pay in USD and likely be up for your credit card provider's fees for converting the USD charge back in to SGD?
A secondary issue is then, given that the booking engine converts the fare into USD, what exchange rate is used. Seems to that using the current bank rate is reasonable.
