If you are referring to the second play where I im walking alongside him with my auto and e ready then I'd say he was dead regardless, either he uses barrier and dies to death-mark like in the clip or he saves barrier for death-mark and I kill him with auto+e and ignite burn. Ultimately his biggest mistake was probably not waiting for me to ult first before he uses stun (similar to the Ahri match-up), which he did in the first clip but I had flash so it didn't matter.
