Current implementation in OpenVZ kernel only tracks synchronous writes. It will not track asynchronous (because the OpenVZ kernel doesn't have support for asynchronous page owner tracking). Reads are always synchronous, that's why read throttling is working. Try mounting the filesystem in synchronous mode and you should see blkio throttle working as you expect. I am not aware of any solution working under the OpenVZ kernel to do asynchronous write throttling. Let me know if you find something that does.
