Really, I assumed that people thought he was invincible because he seems to have the ability to effortlessly defeat anyone who is not Issho as Peridactyl, mentioned above. I have seen fans who have said that it wasn't a real battle and that in a real battle Issho would lose as effortlessly as the rest. There are even people who assume that Zoro has already far surpassed Hawkeye and is merely holding back so as not to embarrass Luffy by effortlessly defeating the Yonko for him. Delusional if you ask me.
