I assumed (probably wrongly) that it is because the fuel is flowing sideways through that big cavity and could puddle in the bottom of the cavity. With the filler, the cavity is smaller and less room to puddle. On other OMC carbs, the discharge holes are on the bottom of the cavity–self draining, so to speak.
