Gooseneck in steam condensate tank vent

LJCLJC Posts: 4Member
If the open vent for a steam condensate tank is indoors, what is the purpose of adding a gooseneck? There's no weather to worry about - is this about dust? If not, isn't it easier to keep possible steam discharge away from personnel if the venting pipe went straight upwards (to a point above the boiler water line)?
This comes from reading through Dan Holohan's The Lost Art of Steam Heating - I think I understand everything else going on with the vent.

    It's about risk of hurting somebody with scalding water. Piping it back to safely close to the floor protects people from being burned by surprise.

    Also pipe acts as a vent on top and an overflow to direct any water to the floor. if traps fail steam could come out both openings
