Well it does kinda matter...when the gussets face down there is a pulling force centered on the welds...and if you are not a good welder there is a chance...although small that the welds could fail...whereas with the gussets going upwards, the forces are in a compression setting and there is less chance of failure....
But really the chance is low to begin with, and if you are a competent welder, it should be fine either way.
