It's not. From the article, it's 96.2% identical. 3.8% different.
"But they also reported that it was 96.2% identical to a coronavirus sequence in their possession called RaTG13, which was previously detected in “Yunnan province.” They concluded that RaTG13 was the closest known relative to SARS-CoV-2.
In the following months, as researchers around the world hunted for any known bat virus that might be a progenitor of SARS-CoV-2, Shi Zhengli offered shifting and sometimes contradictory accounts of where RaTG13 had come from and when it was fully sequenced. Searching a publicly available library of genetic sequences, several teams, including a group of DRASTIC researchers, soon realized that RaTG13 appeared identical to RaBtCoV/4991—the virus from the cave where the miners fell ill in 2012 with what looked like COVID-19.
In July, as questions mounted, Shi Zhengli told Science magazine that her lab had renamed the sample for clarity. But to skeptics, the renaming exercise looked like an effort to hide the sample’s connection to the Mojiang mine."
How did you come by 3.8%?
