That's nonsense. They set their own rules and can change them. My view is that some powerful European nations, including Germany and, when they were still eligible to compete, Russia and Eastern European countries, have stopped them from striking down the proven doped records of the 1980s and early 1990s.
Lord Coe is welcoming it for himself too. In the all-time lists of all track events, athletes from the 80s are:
1) on place 1: Griffith-Joiner + Koch + Kratochvilova
2) on place 2: Kratochvilova + Ozilarenko + Donkova
3) on place 3: Reynolds + Coe + Zagorcheva
That's not a very big group...

This is what he said in 1998:
Britain's Sebastian Coe, a two-time Olympic gold medalist in the 1,500 meters and former world record-holder in the 800, also said it was unfair to conclude that Griffith Joyner used drugs. "I set a world record that lasted 18 years," Coe said. "People do make progress at rates that raise eyebrows. It would be wrong to suggest because an athlete makes a startling breakthrough in a performance, they're cheating." "It's always a balance of judgment and I'm wary of knee jerk reactions," Coe said. "The final arbiter has to be a positive test."
