I can't be sure but the reason might be that US soccer has had three names in its history.
1913-1944- U.S. Football Association
1945-1973- U.S. Soccer Football Association
1974-Current- U.S. Soccer Federation
Just a guess, could be wrong though.
Intreresting. Well, there would be at least some logic then.
