I know that article since David wrote it. The buffer is nice, but it is just a buffer not a part of L1. It just helps to bundle the data in bigger chunks thus some accesses to the L2 can be avoided, nevertheless, you write into the L2.
Or to quote David:
The purpose of the WCC is to reduce the number of writes to the L2 cache,
each Bulldozer module includes a write coalescing cache (WCC), which is considered part of the L2
