ABR Buffer Size of X264 Rate Control

In the abr mode of x264 rate control, a buffer is used. However, the buffer size is changing, which is increasing by step sqrt(fps value), such as sqrt(25), sqrt(30), sqrt(50). I do not understand the reason why the buffer size is variable, rather than a constant? Someone please give me some hints.
