I believe these conditions are only useful in the DEPS file of Dawn. If Dawn is used as a dependency of a larger project, say Chromium, the dependencies of Dawn have already been fetched when processing an upper level DEPS file. In that case, it's unnecessary to download them again in Dawn, and this will be achieved when dawn_standalone is False there.
