The point is that there was exactly nothing of suspicion.
This was to correct the doubt that the HN poster was not the same person as the GitHub user.
Conceding to you that a search can be useful, GP could've stopped at "The github is old and the person has other reputable projects". There was no reason to expand to the LinkedIn.
If there is something of suspicion or not lies in the eye of the beholder.
Only LinkedIn showed the link between the HN profile and the Github profile, because it lists both the project mentioned on the HN profile as well as the project listed in the Github profile.

That may tell more about the beholder than you think.

What if there was no link between the HN profile and GitHub, then? Would you conclude that, because you can't reliably link the HN profile to the GitHub profile (that was independently already trustworthy), this would make the project seem suspicious?
In other words -- Would your projects be more suspicious, if I, a total stranger, made Show HNs about them?
You're seeing my point, don't you?
