This may have to do with the fact that Brazil has some airline regulations that prohibit certain fees for flights originating in Brazil. Not sure of the all details here, but it certainly does not apply on flights US - Europe. If you book that as two one ways Delta will charge YQ on the trip originating in Europe.
