 With the ``build_order_win`` and ``build_order_nix`` being the "build-order" filenames that were used as inputs to the merge, and which will be referenced in the ``filenames`` field of every ``package`` in the build order. This way, it is easier to obtain the necessary command line arguments to build a specific package binary in the build-order when building multiple configurations.

+Note that when a merged build order containing multilpe ``filenames`` something like:

+.. code-block:: json
+
+    {
+        "package_id": "efa83b160a55b033c4ea706ddb980cd708e3ba1b",
+        "context": "build",
+        "binary": "Build",
+        "filenames": [
+            "build_order_win",
+            "build_order_nix"
+        ],
+        "build_args": "--tool-requires=dep/0.1 --build=dep/0.1",
+        "info": {
+            "settings": {
+                "build_type": "Release"
+            }
+        }
+    }
+
+    "profiles": {
+        "build_order_win": {
+            "args": "-pr:h=\"profile1\" -s:h=\"os=Windows\" ..."
+        },
+        "build_order_nix": {
+            "args": "-pr:h=\"profile2\" -s:h=\"os=Linux\" ..."
+        }
+    }
+
+
+Then, the ``filename`` to be used is the first one, in this case ``build_order_win``, because the ``context`` and ``build_args`` arguments matches this profile information. The other filenames are provided as a reference to which other individual build-order files had this ``package_id`` listed for build.
