True, but the top quartile only estimated themselves 6 points higher than the bottom quartile estimated themselves. The top quartile is the only group to actually underestimate their abilities, and do so by over 10 points. Ironically, the third quartile is the most accurate at estimating their own abilities, being almost spot on. The people in the other three quartiles generally also believe they are in the third. To quote liberally from the paper to save everyone reading the whole thing: "As Figure 2 (page 5 of the pdf) clearly illustrates, it was participants in the bottom quartile [...] who overestimated their logical reasoning ability and test performance to the greatest extent. Although these individuals scored at the 12th percentile on average, they nevertheless believed that their general logical reasoning ability fell at the 68th percentile and their score on the test fell at the 62nd percentile. Their estimates not only exceeded their actual percentile scores, [...] but exceeded the 50th percentile as well. [...] Thus, participants in the bottom quartile not only overestimated themselves but believed that they were above average. [...] Other participants were less miscalibrated. However, as Figure 2 shows, those in the top quartile once again tended to underestimate their ability. Whereas their test performance put them in the 86th percentile, they estimated it to be at the 68th percentile and estimated their general logical reasoning ability to fall at only the 74th percentile"
