Please check whether the below logic is correct.
It seems that it uses the GPU command of conditional end for the
subsequent pass. In such case all the commands should be put into one
batch buffer and it is submitted only once.
But the current logic causes that it is submitted multiple times.
[Pengfei] good comments. It will be fixed.

It will be better that this function is defined in Patch_07.
