Seems like he has more than the average number of legs as well.
The fact that he has a wiki page, and that many folks with born without or who have lost legs (~500,000/year Americans experience limb loss or are born with a limb difference https://amputee-coalition.org/resources/limb-loss-statistics...) do not, suggest that the number of people with < 2 is far greater than the number of people with > 2. So the average is still less than 2.
For better or worse, number of legs (or number of arms) is canonical example people use to demonstrate the statistical principal a significant majority of a population can be above average of some metric.
