Yes, but the next few paragraphs are kind of relevant in this context too:
Practising medical specialists such as Addo do not believe this number of unreported cases to be statistically significant. “I have yet to see any data that would suggest a large number of untested corona-related deaths that don’t show up in the statistics,” she said.
“Clinics dealing with respiratory illnesses have been on high alert about the virus for weeks, so I would be very surprised if there was a significant figure of uncharted deaths.”
The RKI’s official mortality figures include both people who have died of the virus as well as those infected and with underlying health problems, where the precise cause of death could not be determined.
Not all countries test all casues of death (Germany, for instance - which may be one of the multiple reasons it's behind the curve).
