One two, first set of hits, three four, second set as in swinging them both at once, swinging them twice.

The way you described it in your post wouldn't work that way... Or rather, it would be really inefficient to do it that way. Since you crumple him forward with the elbow shot, pulling the pistols back up against his chest would be both slower and have less power than just slamming them on his back.

Though that's assuming your side-step elbow actually got through, which is something for a different time.

Food for thought.

EDIT: And yes, that would mean Cassius could feasibly block your 4 hits (or at least just the second set, elbow-stomach stagger is a bitch). Assuming he's not inebriated or anything.
