Why shoud the vbv-related parameters be used in the MB Rate Control in X264?

In the ABR RC mode of x264, we just need give the parameter --bitrate, and this is Frame Level Rate control. But when I want to use the MB Level RC (not MB-tree), I have to give the parameters of vbv-bufsize and vbv-maxrate. I can't understand why? Is it impossible to use the MB Level RC with just the parameter --bitrate and HOW?
Can anyone give me some hints or explanation or whatever?
