Tests on real hardware say that it does. Since g4x can't send infoframes to more than one HDMI port anyway, we don't lose anything by allow it. For PCH platforms BSpec explicitly forbids HDMI+HDMI cloning. Whether HDMI+HDMI cloning might also work on VLV is a bit unclear, but since we'd at least lose the capability of sending infoframes to more than one cloned HDMI port, it doesn't seem like a good idea to allow it.
