Assuming you are referring to the virtual memory used by the container ...
The cgroup memory acts at the physical memory level. What you assign is 
the physical memory for your container.
For example, if you have 2GB of memory on your host, you can assign 
512MB to your container and 1,5GB will be available for your system. But 
the processes will still have 4GB (for a 32b host) of virtual memory.

So what you see is the physical memory used by the container.
