That article does not say anything about Nixon claiming to have sent men to the moon 4 times. It’s talking about the space shuttle program, which has never gone to the moon and isn’t designed to. Space shuttles are restricted to low earth orbit only.
A total of 6 crewed missions landed on the moon during Nixon’s presidency; Apollo 11, 12, 14, 15, 16, and 17. Dozens of unmanned landings, unmanned flybys, and crewed flybys of the moon all happened before, during, and after the manned landings on the moon.
Nixon was the only President to claim to have "sent men to the moon" (4 times).
