That link does not work - try again and insert the picture if you can so we can see what you mean.
I work with the A346 just about every day, and to be honest I can't say I've ever noticed, although they do sit pretty low to the ground, I'll have a look next time I'm in ( but not for 2 weeks tho - on holiday now)
The only reason I can think of based on your description is that aircraft in general fly in a slightly nose up attitude, so then the slight downward angle on the engines would mean that they are able to achieve maximum airflow in the cruise as they would be paralel to the oncoming airflow, which after all is where they spend most of their running time.
Just my thought's.

The same effect can be seen on other aircraft types as well; In many cases, the engines are canted horizontally rather than vertically. And the only reason I know of is indeed the airflow at the location where the engines are mounted.
There is no benefit to mounting the engines pointing straight forward if the airstream in cruise doesn´t follow the same straight line (due to the "bow wave" created by the fuselage, for instance).
