Does the comment actually say that, though? It would make sense if the comment said that, but e.g.
> perform antivirus comparative analyses
is not what is happening here.

It says right in the parent comment that the VT results may not actually reflect how the product performs in the real world.
-VirusTotal's antivirus engines are commandline versions, so depending on the product, they will not behave exactly the same as the desktop versions: for instance, desktop solutions may use techniques based on behavioural analysis and count with personal firewalls that may decrease entry points and mitigate propagation, etc.
-In VirusTotal desktop-oriented solutions coexist with perimeter-oriented solutions; heuristics in this latter group may be more aggressive and paranoid, since the impact of false positives is less visible in the perimeter. It is simply not fair to compare both groups.
-Some of the solutions included in VirusTotal are parametrized (in coherence with the developer company's desire) with a different heuristic/agressiveness level than the official end-user default configuration.
