Actually, this is NOT what I see (in Xcode 3.x!). Command-double-click brings me to the definition, not to the docs.
But let me defend Apple's choices, because I think it makes sense. The change I see between Xcode 3 and 4 is that for single modifiers they replaced the double-click by simply showing a link and allowing a single click. This is generally a very big improvement: 1. it is intuitive, because you see the link, so it's very easy to discover by accident (pressing a modifier and two clicks is very far from discoverable), 2. it requires one click less. However this is slightly different for the Option-Command modifier: instead of showing the docs, it shows the definition in the Assistant mode. Apparently they thought that made more sense, because it (Assistant) is a feature that is present in Xcode 4 and wasn't in Xcode 3, and moreover getting to the docs is just one click extra away (in Quick Help). So maybe it's not to your liking, but it does make sense.
However, I would like to add/admit that they could have easily improved the situation by providing the direct link to the docs without the intermediate popup, for instance using Shift-Option or some other unused modifier combo. Perhaps if we all ask for it they might add it in 4.1.
