That doesn't mean anything. One panel after each other could be a 10 year timeskip.
Not that this would make any difference anyhow if he is shooting at Rakuyo or some other no name offscreen fodder, but yea I'm pretty sure Oda was showing the passage of time/ individual events with the panels to convey how the war was raging on. He added that little panel of bodies in between Rakuyo attacking Kizaru and Kizaru shooting his laser to portray turmoil.
Not that it matters either way.
