Is ALBERT the right implement from paper ?  
I read ALBERT paper and code form Google: github.com/google-research/ALBERT. One of the main contribute of ALBert is cross-layer parameter sharing and i can see it on Google's code. But i can't see sharing on this code. Every Layers(or Blocks) are new object and their parameter will be different after fine-tuning.

Is the implement is wrong or i have misunderstanding about parameter sharing?
I read the code carefully, and it do share.
