Cause as RED RANGER pointed out himself, That Chart just shows of Kamen Rider lead's who have become famous after that series has ended. The fact that Kento Handa is returning is just a coincidence. (If you really believed that chart, then Odagiri Joe would be returning as well, and As we know by now, he's not).
Edit:
Also, by your logic, Koji Seto's not returning because his name isn't on the list.
