A question about a recipe: Zesty Citrus and Olive Pork Roast

I have a question about step 2 on the recipe "Zesty Citrus and Olive Pork Roast" from groceryalerts. It says:

"Stuffing and Arranging the Roast:

Make the stuffing paste with pitted green and kalamata olives. Chopping up the olives, orange zest with my emerging blender adding 2 tblsp of olive oil and one orange juice freshly squeezed. Then arranging the prosciutto evenly over the pork. Now the paste – spreading the olive paste over the prosciutto evenly and adding on the lemon and orange slices over the paste."
