I fully agree that 1000kbps is way too low for 4K footage (except stills).
But that is not the point of this benchmark since nobody is going to watch the output anyway.
The point is to balance the different parts of the x264 code such that it is representative of a larger set of similar behaving software.
I don't know all the effects, but I know that if you increase bitrate, you get a higher percentage of CABAC in your profile. And CABAC is likely not very representative of the code the "x264" test should represent.
