Yoma 55: One and One, One and Two

The sprinkling of the blood of the bull and of the goat, in great detail - as it also appears in the Yom Kippur liturgy. How does the kohen gadol count? Of course, it's a machloket. What IS the point of counting out loud? Plus, the bowls of blood from the bull and the goat, to be placed on the pedestal. Or the two pedestals. But there is no clear information whether there was one or two! Also, a parallel to horns for collecting funds - but just one, to ensure there won't be confusion, where labeling the horns is insufficient (for R. Yehuda). So too with the pedestal - labeling would be insufficient, to make confusion absolutely impossible.
