Uh, I regret to inform you that I found the name from the autocomplete and then hit tab. It was not on the tip of my tongue and you can easily reproduce the experiment if you don't believe me.
Note that there's no reference to his real name.
The only reference to his real name in your screenshot is the first entry, which is purple and removable because it is coming from your browser's session identity history. If this was in fact in an incognito tab, it's likely you had one or more incognito windows simultaneously open somewhere else where you had searched for him, which carried over into your new tab.
I did this on a computer I don't usually use in an incognito tab.
He is not "the target audience" for this sort of thing.
