Though worth bearing in mind that even in the worst case scenario, the debris cannot have a perigee that is higher than the impact point of 280km.
I don't follow either the Newtonian logic, nor the relevance of this. Would you be so kind as to expand please? Or did NASA get it wrong?

In the sharpest rebuke to date by a U.S. government official, NASA Administrator Jim Bridenstine criticized India’s recent anti-satellite test April 1, saying it created debris that posed a threat to the International Space Station. During a town hall meeting with NASA employees, Bridenstine was asked about the March 27 test, dubbed “Mission Shakti,” where a ground-launched missile struck the Microsat-R satellite in an orbit less than 300 kilometers high. The Indian government said the low altitude of the test minimized the amount of long-lived debris. Bridenstine, though, said that the test did produce some debris placed into higher orbits, including those above that of the ISS, which orbits at an altitude of about 410 kilometers. He said 400 pieces of debris had been identified from the test, 60 of which are large enough to be tracked by U.S. military assets, such as radars. “Of those 60, we know that 24 of them are going above the apogee of the International Space Station,” he said. “That is a terrible, terrible thing, to create an event that sends debris into an apogee that goes above the International Space Station. And that kind of activity is not compatible with the future of human spaceflight.”
