Why only 1/1250s @ f2.8 on DP2 Merrill?

So we finally had a sunny day yesterday and I wanted to take a picture at f2.8 on my DP2 Merrill. I had the dial on M and as it was very bright I just dialed in a fast shutter speed (like one I would normally use on the SD1) ... took the picture and it turned out dark. I got suspicious and then I saw in the viewfinder that suddenly the aperture was set on f4. Ok, I thought that I must have done something wrong and after playing a bit more around I realized that even in M the DP2 increases that aperture when you dial in a very fast shutter speed ... and then I remembered that it said something about this in the instructions.

Now, this basically meant that I couldn't take the picture like I wanted. I'd like to understand the reason behind limiting the shutter speed like this? If I want to take a portrait shot on a bright day at f/2.8 I can't because it's not possible (unless I happen to have a ND filter with me which I would have to buy in the first place).

Looking at the instructions it says that from f2.8 to f3.5 you can only have a shutter speed as fast as 1/1250s, from f4 to f5 1/1600s and finally from f5.6 to f16 1/2000s.

So why can I not have 1/2000s at f2.8 where I am more likely to use it than at f5.6?
