Yes, I'm aware of that.
The International Committee on Taxonomy of Viruses has an informative article on the naming of the coronavirus:
International Committee on Taxonomy of Viruses (ICTV)
The following table is what I'm getting at:
"Naming the 2019 Coronavirus"
https://talk.ictvonline.org/cfs-file..._home/SARS.png 
The virus causing the current outbreak of coronavirus disease has been named "severe acute respiratory syndrome coronavirus 2" (SARS-CoV-2). The manuscript describing the name also reports the work of the ICTV Coronaviridae Study Group (ICTV-CSG) that determined the virus belongs to the existing species, Severe acute respiratory syndrome-related coronavirus.
So, if SARS-CoV was called SARS why isn't SARS-CoV-2 called SARS-2?
Simply because that naming falls to WHO and they didn't want to cause a panic by making it clear that SARS was back.
In point of fact they even refuse to refer to the virus by its correct ICTV name - they refer to it obliquely as:
“the virus responsible for COVID-19”
Shades of "he who must not be named". They've managed to remove "SARS" from both the name of the virus and the disease it causes.
And why? Because, from the WHO page you linked to:
"From a risk communications perspective, using the name SARS can have unintended consequences in terms of creating unnecessary fear for some populations, especially in Asia which was worst affected by the SARS outbreak in 2003. For that reason and others, WHO has begun referring to the virus as “the virus responsible for COVID-19” or “the COVID-19 virus” when communicating with the public. Neither of these designations are intended as replacements for the official name of the virus as agreed by the ICTV."
It was when I was working on this stuff in late January this year that it became clear that WHO is very much as political as medical.
