The Gemora is discussing cases where one switches around the order of the bull and the goat, does he have to start all over again. At one junction in the Gemora, we think that the case is as follows: the kohen sprinkles the blood of the bull on the mizbeach before he sprinkled the blood of the goat on the Paroches in the Heichal.
QUESTION: what happened in this case? Normally, the two bloods are mixed together and sprinkled on the Mizbeach after he completed all the sprinklings on the Paroches. Here, that can't be the case because he subsequently went and sprinkled the blood of the goat on the Paroches afterwards and presumably this was done by itself. If he did not mix the blood, then how could he sprinkle the blood of the Par on the Mizbe'ach? What was done?

Beautiful question! Perhaps that is one of the reasons for the Vilna Gaon's erasure of this section of the Gemara. (However, all of the Rishonim and Kisvei Yad have the section.)
Perhaps the Gemara is suggesting that the Beraisa maintains "Ein Me'arvin le'Keranos," the blood is mixed after sprinkling on the corners of the Mizbe'ach and before sprinkling on the top of the Mizbe'ach (see Yoma 57b).
Be well,
