A question about a recipe: GREEN CHILI, CHICKEN, POSOLE SOUP

I have a question about step 4 on the recipe "GREEN CHILI, CHICKEN, POSOLE SOUP" from dymnyno. It says:

"In a blender, put the sauteed onions, the garlic cloves, about a third to half of the cooked posole, 3 tablespoons of fresh oregano, the peppers and 4 cups of the chicken stock and blend until smooth. (you may have to do a couple batches)"

I am embarrassed to have another question about posole. Do you strain the liquid from the cooked posole and/or use it with the chicken stock?
